Gillette Rubie Plus Razor Blade

Gillette Rubie Plus Razor Blade Review

Initially I had reservations about using Gillette DE razor blades when I started traditional wet shaving using a safety razor, my plan was to escape Gillette as I was mad at them for charging so much for cartridges. As it turns out Gillette makes quite a few DE razor blades, and the Gillette Rubie Plus is one of them. (I have also seen the package labelled as Gillette Rubie Platinum Plus, which is also on this particular blade itself).

I have been quite happy overall with the different Gillette DE razor blades. There are so many, and it appears to me that there happen to be slight differences between them all which explains the selection.

The last 2 DE razor blades I tested were not very sharp, so I was hoping the Gillette Rubie Plus would change the pace a bit. Sharpness is not the only criteria for me, but overall I do prefer a blade with somewhat of a sharper reading.

Fresh out of the pack the sharpness measured 50, which is not very sharp. This is actually the least sharp Gillette blade out of the package that I have tested so far, there have been 8 others. You can click this link to see a Razor Blade Sharpness Comparison Chart with the other blades tested so far.

I was not overly concerned as many blades sharpen up with use, however I do tend to like razor blades in the mid 40’s or lower. (Remember, a lower reading is a sharper blade).

Note that I shave my head as well as my face and have a pretty thick growth – except for the top of my head. This means that one of my shaves might equal two of someone that just shaves their face, or even more if they have a thinner beard.

The first shave was very ordinary. It was not bad, it was not great, I shaved. Some people can make any razor blade work for them, I tend to have a wide range of experiences. Some blades I rave about and I am reminded why I use a DE, some blades are awful and I would throw them out half way if I wasn’t collecting data. The Gillette Rubie Plus was somewhere in the middle, but I did not find it quite sharp enough or overly smooth.

After the first shave, the sharpness increased to 45. You will notice in the other razor blade reviews as well that most blades so far tend to sharpen up with use, and this is another example of about a ten percent increase in sharpness. Perhaps there was still hope for this blade.

The second shave was quite a bit different than the first shave, and in a very positive way. It sharpened up enough to cut through my growth a lot better than the first round. I would say the second shave was great.

After the second shave the sharpness increased again to 41. This confirms, in my opinion, why the second shave was substantially better as shave one was shaving in the high 40’s and shave two was shaving in the low 40’s.

Initial Sharpness = 50
Average Sharpness = 45
Edge Retention = 0.82
Smoothness = 3/5

Overall Subjective Rating = 3/5

Platinum Coated. Made in Russia.

I have run into this before where the first shave is not that good, but the second shave is great. Many people use each DE blade several times, and don’t mind toughing through one inferior shave to break in a blade.

I personally usually only use a DE blade twice, and because of the price of DE razor blades in general I don’t plan on using them any longer. Based on this, it does not make sense for me to go through an inferior shave when I can use other blades and get a great shave for less than ten cents (per shave, not necessarily per blade).

As always, your mileage may vary and my review is mainly to provide the sharpness data relative to other DE razor blades.

Derby Premium Razor Blade

Derby Premium Razor Blade Review

This review is for the Derby Premium double edge razor blade. This post will also serve as somewhat of a comparison to the popular Derby Extra razor blade, both for the empirical sharpness data and my personal user experience.

The Derby Extra razor blade is a very popular razor blade, although it does have very mixed user reviews. Although it is not the sharpest blade and I personally wasn’t able to get more than one good shave out of it, it does have a reputation of being very mild in the way of not instigating any irritation for even very sensitive skin.

The Derby Premium razor blade has the same Chromium-Ceramic, Platinum, Tungsten and Polymer coating as the Derby Extra, but also advertises Swedish Steel on the package.

Fresh out of the pack the sharpness measured 51. For information on what this means check out Razor Blade Sharpness Testing. This is only marginally sharper than the Derby Extra 53, and the concern arose that this might just be the same Derby Extra with different branding. You can click this link to see a Razor Blade Sharpness Comparison Chart with the other blades tested so far.

I find around the 50 mark is where I can notice the lack of sharpness in a razor blade, and the first few strokes it certainly did not feel sharp. It seemed to sharpen up quickly however, and I proceeded to have a great first shave with no nicks or irritation.

Note that I shave my head as well as my face and have a pretty thick growth – except for the top of my head. This means that one of my shaves might equal two of someone that just shaves their face, or even more if they have a thinner beard.

After the first shave, the sharpness increased to 46, which is very close to the Derby Extra value of 44 after the first Derby Extra shave. I also had a great first shave with the Derby Extra, so again I started to think these blades might just be basically the same.

The second shave is where there is a noticeable difference between the Derby Premium and the Derby Extra razor blades. While the Derby Extra second shave was noticeably dulling towards the end, the Derby Premium continued to perform. I had an excellent full head and face shave that was just as great as the first shave.

After the second shave the sharpness stayed the same at 46, compared to the Derby Extra dropping down to 51. This small difference was enough for me to noticeably have a much better shave on the second round with the Premium blade.

Initial Sharpness = 51
Average Sharpness = 48
Edge Retention = 0.90
Smoothness = 5/5

Overall Subjective Rating = 5/5

Stainless Steel, Chromium-Ceramic, Platinum, Tungsten, Polymer Coated Edges. Made in Turkey.

While writing this review I did a quick search for the pricing of the Derby Premium Razor Blades. I found a 100 pack for $8 USD/$10 CDN with free shipping on Amazon and I took a break to order a pack. At 5 cents a shave for 2 great full head and face shaves, that is a bargain and one of the reasons I like using a safety razor.

The fact that I got 2 great shaves with no nicks or irritation earned the Derby Premium 5 stars from me. I would have liked it to be slightly sharper to be considered a premium razor blade over all, but it certainly is a premium Derby blade, if that makes sense.

One note of caution is that I can see potential issues in a mild safety razor due to overall sharpness still being somewhat on the lower end.

That said, I definitely recommend giving the Derby Premium razor blade a try. It’s just that little bit sharper and holds its edge better than the Derby Extra.

Treet Black Beauty Razor Blade

Treet Black Beauty Razor Blade Review

The Treet “Black Beauty” razor blade caught my eye as soon as I started shaving with a safety razor. The novelty of the black blade combined with the incredibly low price was enough for me to go out on a limb and purchase 100.

My initial shave with the Treet Black Beauty did not go well. I had been using a safety razor long enough to know that it felt dull, but it was still early enough that I accepted the possibility is was poor technique or just not the right razor (I was using an Edwin Jagger DE86-BL).

I have been eagerly waiting for months for the Treet Black Beauty to be voted for testing. When I initially tried the Derby Extra I also did not find it very sharp in the Edwin Jagger, however I ended up getting great shaves in the Merkur 34C or Merkur 37C. I was hoping that the same thing would happen to me with the Treet Black Beauty using the 34C for the sharpness testing.

Fresh out of the pack the sharpness measured 52, which is not very sharp. This is exactly what I was expecting, although I was thinking that it might even be the least sharp yet (the Rockwell Razors still holds the least sharp out of the package title at 54). You can click this link to see a Razor Blade Sharpness Comparison Chart with the other blades tested so far.

The first shave with the Treet Black Beauty was awful.

Note that I shave my head as well as my face and have a pretty thick growth – except for the top of my head. This means that one of my shaves might equal two of someone that just shaves their face, or even more if they have a thinner beard.

I ended up getting a somewhat passable shave on my head, although it was very inefficient. It took a lot of effort to get to a point where I felt I could quit, but it was nowhere near baby smooth. By the time I got to my face I felt like I was attempting to scrape the hair off.

The first shave was unacceptable. I was not even able to get remotely close on my chin and jaw, it was like the razor blade was literally doing nothing – as if I was just dragging a spoon across my face. I could feel it moving across my chin, but it wasn’t really doing anything.

As we had plans to go out for dinner with friends, I mentioned my shave to my wife. She said she noticed already and thought that maybe I was trying something new, and didn’t want to be mean by saying anything (mainly that I looked insane). I ended up putting a Voskhod into another safety razor to clean up for dinner.

After the first shave, the sharpness decreased to 62. You will notice in the other razor blade reviews as well that most blades so far tend to sharpen up with use, however this blade took a drastic decline.

I was dreading the second shave, and was racking my brain to figure out how I could get away without performing the second shave test. Unfortunately (for me) there was no way around it. I had to do a second shave to get the results.

The second shave was truly a demonstration of commitment to the razor blade sharpness testing. The best I could do was attempt my 3 pass shave on each my head and my face, and then when my skin had enough I cleaned up with a Voskhod that was already loaded in another razor.

Using the Voskhod was actually remarkable when using immediately after the Treet Black Beauty, just how easy it worked compared to the Treet doing nothing.

I have now tested over 25 different DE razor blades to date, and the Treet Black Beauty is the first razor blade time that I actually had to use another blade to finish. There was no way I could go for dinner after the first shave or work after the second shave looking how the treet Black Beauty left me.

After the second shave the sharpness decreased again to 69, which is by far the lowest sharpness reading to date. I literally have nothing good to say about the Treet Black Beauty, I don’t even think it looks cool anymore.

Initial Sharpness = 52
Average Sharpness = 61
Edge Retention = 1.33
Smoothness = 0/5

Overall Subjective Rating = 0/5

Carbon Steel. Made in Pakistan.

The majority of the razor blades that I test will by definition be average. While there may be some interest on which side of average they fall or potential anecdotes that arise from my shaves, the true value or interest in my opinion will be the blades that are very sharp or very dull. These are the blades that may be desired or avoided depending on the individual shavers preference.

I know that your mileage may vary, but I do not see how anyone with a relatively coarse or thick beard could get a remotely reasonable shave in a mild to moderate razor using the Treet Black Beauty.

Even when I don’t like a blade I usually recommend giving it a whirl, however this is a case where I would not. Ignore the siren calls of the Treet Black Beauty with its unique look and very desirable price – fill your ears with wax and avoid the shipwreck.

Gillette Wilkinson Sword

Gillette Wilkinson Sword Razor Blade Review

There are at least 2 different DE razor blades branded as a Wilkinson Sword – Wilkinson Sword and Gillette Wilkinson Sword.

The first Wilkinson Sword I tried is made in Germany and is a fantastic razor blade that is widely available, including even at the pharmacy or grocery store – which is great.

This review is on the “other” Wilkinson Sword, that is branded as Gillette and I only see online. It has also been labelled the “Indian” Wilkinson Sword, however after reading the package it appears to be made in China and imported to India. This particular blade was then sold to tryablade.com in the USA and made its way to me in Canada.

This website will be listing this blade as Wilkinson Sword Gillette in lists and tables – primarily to distinguish from the other Wilkinson Sword, and Gillette will be last so that the Wilkinson’s are beside each other for easy comparison.

Another Gillette blade that is made in India is the Gillette 7 O’clock Super Platinum (Black), and I like the German Wilkinson Sword quite a lot so I was optimistic going into this razor blade test.

Fresh out of the pack the sharpness measured 43, which is right about average. This is also slightly sharper than the German Wilkinson Sword that came in at 46, but note the German blade has a PTFE coating which wears away quickly. You can click this link to see a Razor Blade Sharpness Comparison Chart with the other blades tested so far.

The first shave with the Gillette Wilkinson Sword razor blade was great. I did my usual 3 pass shave and was able to get a very smooth and close shave all over with no nicks, cuts or irritation.

Note that I shave my head as well as my face and have a pretty thick growth – except for the top of my head. This means that one of my shaves might equal two of someone that just shaves their face, or even more if they have a thinner beard.

After the first shave, the sharpness increased to 40. You will notice in the other razor blade reviews as well that most blades so far tend to sharpen up with use. This is only slightly sharper than the initial sharpness of 43, and I very much like the consistency.

I find anything in the high 30’s or low 40’s is a great shave, and I am not really a fan when blades really sharpen up as I personally shave differently with a blade that is 45 than a blade that is 35. Consistency in my opinion is great as the shaving technique does not require any adjustment along the way.

The second shave was basically the same as the first and was a great shave. Close, smooth, and no irritation.

After the second shave the sharpness decreased just slightly to 41, which for all intents and purposes is the same as 40. Again I will note the consistency, it basically did not change much at all out of the package – and was sharp enough for great shaves the whole time.

Initial Sharpness = 43
Average Sharpness = 41
Edge Retention = 0.95
Smoothness = 5/5

Overall Subjective Rating = 5/5

Platinum Coated*. Made in China, imported to India.

*While I did not find an “official” source to confirm Platinum coating, I did find several unofficial references.

I can see why these blades are called the Indian Wilkinson Sword as they are imported to, and would be purchased from India. That said, the many references online that state made in India are simply false as the package clearly states they are made in China. Perhaps they were once made in India and the manufacturing was moved, and the name just stuck.

Regardless of where they are made, the Gillette Wilkinson Swords are a fantastic razor blade, very reasonably priced, and I suggest that you give them a try.

Rockwell Razors Stainless Steel Razor Blade

Rockwell Razors Stainless Steel Razor Blade Review

Rockwell Razors manufacture some very popular Safety Razors, and they also have a line of razor blades. While I have heard nothing but positive feedback about the safety razors, the reviews on the Rockwell Razors Stainless Steel Razor Blade have been going either way.

I would have preferred to have my first shave with a Rockwell Razor Blade in a Rockwell safety razor, however all the sharpness testing is completed using a Merkur 34C to keep the experience and results consistent.

One thing that I am not a fan of however is that they are branded as “Swedish Stainless Steel” but everything that I can find says they’re made in China using Swedish stainless steel. I was not able to find anything on the Rockwell site to confirm where they are made so if someone has a link please comment below and I will update.

Fresh out of the pack the sharpness measured 54. This is the least sharp blade of any tested to date out of the pack.

For information on what this means check out Razor Blade Sharpness Testing. You can click this link to see a Razor Blade Sharpness Comparison Chart with the other blades tested so far.

Note that I shave my head as well as my face and have a pretty thick growth – except for the top of my head. This means that one of my shaves might equal two of someone that just shaves their face, or even more if they have a thinner beard.

The Rockwell Razors Stainless Steel Razor Blade shaved like a dull blade. While there was fortunately not really any tugging, I did feel like I had to work harder. I find that a sharp razor blade almost just slides over the skin with just the weight of the razor as it cuts through, while a dull blade needs to be helped along. The saving grace was that I did get a reasonably close and comfortable shave with no irritation, it just took some effort.

After the first shave, the sharpness increased to 51. While it was heading in the right direction, anything in the 50’s is not sharp enough for my liking.

The second shave was very similar to the first shave. It did not feel sharp, I had to help it along, but again it was reasonably close and comfortable with no irritation. All in all I would prefer not very sharp and no irritation over getting cut up and irritated, but it is still not ideal.

After the second shave the sharpness decreased back to 54 which is the same as the initial measurement. This results in an average sharpness of 53, which makes the Rockwell Razors Stainless Steel Razor Blade the least sharp blade tested to date, both for initial sharpness and average sharpness.

Initial Sharpness = 54
Average Sharpness = 53
Edge Retention = 1.00
Smoothness = 3/5

Overall Subjective Rating = 3/5

Stainless Steel. Made in China*.

I will say that the Rockwell Razors Stainless Steel Razor Blade was at least consistent, and if one does like a blade that is not very sharp then that is a positive.

It is also recommended to be used with one of the Rockwell safety razors (of course), which does make sense as the Rockwell safety razor has 6 levels of adjustment which may be used in increase the aggressiveness of this blade. Perhaps it would be much better on a very aggressive setting.

Astra Superior Stainless Razor Blade

Astra Superior Stainless Razor Blade Review

One of the first razor blades I tried was the Astra Superior Platinum in the green package. I really tried to like the Astra SP based on the user reviews,  wide availability and great price, but I have yet to have a great (or even good) experience and frankly dislike the Astra SP.

Now this review isn’t about how much I don’t like the Astra Superior Platinum, it is the sharpness testing and my user review of the Astra Superior Stainless – the one in the blue package.

To be honest I’ve been dreading testing the Astra Superior Stainless since I typed it into the poll, and this is purely based on my experience with Astra SP blades. That said, it is important to go into testing anything with an open mind and no bias, otherwise ones preconceived notions may skew the experience and then what’s the point?

Fresh out of the pack the sharpness measured 43. This is actually a decent amount sharper than the Astra SP at 49 so I was cautiously optimistic. Also to be clear, I did not like the Astra SP as I did not find it sharp or smooth enough to satisfy my requirements for a good shave.

For information on what this means check out Razor Blade Sharpness Testing. You can click this link to see a Razor Blade Sharpness Comparison Chart with the other blades tested so far.

Note that I shave my head as well as my face and have a pretty thick growth – except for the top of my head. This means that one of my shaves might equal two of someone that just shaves their face, or even more if they have a thinner beard.

The first few strokes actually felt pretty good and I even enjoyed the anticipation of wondering which direction this shave would go. I proceeded to have an absolute amazing first 2 passes on my head. When I completed my second rinse, it was actual so close and smooth that I really only needed some clean up.

I continued with my 3 pass shave on my face and it was the same – sharp, smooth, and down right amazing. I also had basically zero feedback with my Osma Alum Block.

Admittedly the bar was set very low (I was expecting a very poor shave) but my expectations were blown out of the water.

After the first shave, the sharpness increased to 38. This is right in the area where I like a blade to be, the high 30’s or low 40’s. The Astra SP was 44 after the first shave, so this Astra SS kept its 6 point lead after each had one shave.

The second shave was also great. Based on the complete surprise from round one I don’t think anything really could have been better than the first shave, but it was fairly consistent although I did need my full third pass on my head this time. Still excellent.

After the second shave the sharpness decreased to 40. The Astra SP measured 44 after the second shave, so while the Astra SP was still sharpening up the Astra SS was starting to decrease after the second shave already – which is fine, I toss my blade after two shaves anyways so I was happy.

Initial Sharpness = 43
Average Sharpness = 40
Edge Retention = 0.93
Smoothness = 5/5

Overall Subjective Rating = 5/5

Stainless Steel. Made in Russia.

I find quite often that when something is too hyped up it is almost a fault as it is difficult to fully achieve the expectation that has been set in ones mind. On the other side of that coin, having no interest or even expecting the worst can result in an amazing experience when things work out well.

The Astra Superior Stainless Razor Blade exceeded my expectations, and in my opinion is infinitely smoother than the Astra Superior Platinum – and sharper. I also looked online and found them to also be readily available and reasonably priced, I will be ordering another 100 for my reserves and highly suggest you give them a try.

Bic Chrome Platinum Razor Blade

BIC Chrome Platinum Razor Blade Review

The BIC Chrome Platinum Razor Blade is one DE blade that I have been waiting to test since I started this project.

BIC is a very popular brand, so much that it has been able to become a verb in relation to shaving one’s head. The term “BIC it” is even on Urban Dictionary and I think most people would know what is meant by the term BIC your head.

There seem to be lots Russian, German and Indian blades, but the BIC Chrome Platinum Razor Blades are made in Greece.

Fresh out of the pack the sharpness measured 40. This is really sharp out of the package and I was even more excited to give it a try. The average sharpness to date is around 45, with readings ranging from 32 to 53 (Note Feather is 32 and the next sharpest is 39).

For information on what this means check out Razor Blade Sharpness Testing. You can click this link to see a Razor Blade Sharpness Comparison Chart with the other blades tested so far.

Note that I shave my head as well as my face and have a pretty thick growth – except for the top of my head. This means that one of my shaves might equal two of someone that just shaves their face, or even more if they have a thinner beard.

The first shave with the BIC Chrome Platinum was fantastic. As usual I did my 3 pass head then 3 pass face shave and had no nicks, cuts or irritation. It was very smooth and was very impressed with the first shave.

After the first shave, the sharpness increased to 33. This makes the BIC one of the sharpest blades out of the package as well as one of the sharper blades after the first shave.

The second shave was also great, and noticeably sharp after the second shave. I would be comfortable using the BIC Chrome Platinum for a third full head and face shave.

After the second shave the sharpness increased again to 32, which for all intents and purposes is the same as after the second shave at 33. What is interesting here is that to date, only 5 other razor blades have measured 35 or sharper after the first shave. In all 5 cases the razor blades came in less sharp after the second shave, where the BIC Chrome Platinum was even able to increase a point.

Initial Sharpness = 40
Average Sharpness = 35
Edge Retention = 0.80
Smoothness = 5/5

Overall Subjective Rating = 5/5

Chrome Platinum Coating. Made in Greece.

I enjoyed using the BIC Chrome Platinum Razor Blade, and was happy after all these years I finally got to “BIC my head”. While Feather still holds the title of sharpest DE Razor Blade out of the package, the BIC Chrome Platinum at the time of testing is the sharpest blade based on average sharpness.

It’s up to you whether you think the sharpest razor blade is out of the package or an average of a few shaves. Either way I do think the BIC Chrome Platinum is more smooth, gives more shaves, and is much more reasonably priced than the Feather. (I still like Feather but I only get one expensive shave out of them). I highly suggest you give the BIC Chrome Platinum Razor Blade a try.

Gillette Nacet Stainless Razor Blade

Gillette Nacet Stainless Razor Blade Review

It’s actually quite interesting just how many different DE razor blades Gillette makes, and if you really start looking into it there are even a lot of DE razor blades that are not branded as Gillette but still made by Gillette.

Initially I tried to stay clear of Gillette because I wanted to get away from anything that reminded me of an expensive cartridge, but Gillette clearly knows what they’re doing which is why they are such a big name. I have been fortunate to have had very good results from most Gillette blades that I have tried and am always looking forward to trying another.

The last 2 blades that I tested were the Merkur and Bolzano, and they were 2 of the least sharp razor blades that I have tried so far. I still had decent shaves with them but I do like my razor blades to be a bit more on the sharp side. The Gillette’s have been pretty good so far so I was looking forward to trying the Gillette Nacet Stainless razor blade.

Fresh out of the pack the sharpness measured 39. This is really sharp out of the package, the only other blade that has been sharper to date has been the Feather.

For information on what this means check out Razor Blade Sharpness Testing. You can click this link to see a Razor Blade Sharpness Comparison Chart with the other blades tested so far.

Note that I shave my head as well as my face and have a pretty thick growth – except for the top of my head. This means that one of my shaves might equal two of someone that just shaves their face, or even more if they have a thinner beard.

The first shave with the Gillette Nacet Stainless was great. After several not so sharp shaves it felt excellent to be using a really sharp blade. As usual I did my 3 pass head then 3 pass face shave and had no nicks, cuts or irritation.

After the first shave, the sharpness increased to 35. Most blades tested to date have sharpened up after the first use and the Gillette Nacet was no exception. I also like that this reading is fairly consistent with the initial reading.

The second shave was basically the same as the first, I was able to achieve basically the exact same results. The Gillette Nacet was still noticeably sharp at the end of the second shave, and I would have no hesitation having a third shave with this blade if I needed to.

After the second shave the sharpness decreased to 38, which for all intents and purposes is the same as the initial reading. Again, I love the consistency here which gave me 2 great shaves.

Initial Sharpness = 39
Average Sharpness = 37
Edge Retention = 0.87
Smoothness = 4/5

Overall Subjective Rating = 4/5

Stainless Steel. Made in Russia.

Overall I enjoyed using the Gillette Nacet Stainless and it turned out to be one of the sharpest blades so far. The Feather remains the sharpest out of the package but the Gillette Nacet ties the Feather for average sharpness and is more consistent.

If you like really sharp DE razor blades then you will want to give the Gillette Nacet Stainless a try.

Merkur Razor Blade

Merkur Razor Blade Review

I have been conducting every razor blade sharpness test using the Merkur 34C, and every Merkur Safety Razor comes with one Merkur Razor Blade. Now since I only had singles I unfortunately did not have the actual package to take my usual picture for this review, but I was lucky enough that the good people at Kent of Inglewood hooked me up with a free pack of Merkur Razor Blades.

I was pretty excited to try the Merkur Razor Blades because there are extreme views online about the performance. I had a little bit of a surprise when I opened the first blade (notice the top edge):

Merkur Razor Blade Edge Coating

I wasn’t sure if it was mechanically damaged or if was a build up of coating. As I squinted and stared I realized I had 10 more blades so I would just wipe it. It turns out it was just a build up of coating and the edge looked okay. The blade itself is likely fine, but since it is not recommended to wipe blades I grabbed a fresh one for testing. The new one looked normal as can be seen in the main picture.

Fresh out of the pack the sharpness measured 53, which is not very sharp. For information on what this means check out Razor Blade Sharpness Testing. You can click this link to see a Razor Blade Sharpness Comparison Chart with the other blades tested so far.

The first shave was not bad, but the Merkur razor blade definitely shaved like a blade that is not very sharp. I do not like to use the term dull as we are still talking about razor blades and they’re all sharp, but comparatively it is on the bottom end of sharpness compared to the other 20 blades tested to date.

I can usually tell when a razor blade is around the 50 mark as I have trouble getting a close smooth shave around my goatee area. Although it was not a very close shave in this area, I did not get any irritation or nicks anywhere which is always the top priority for my shaves.

Note that I shave my head as well as my face and have a pretty thick growth – except for the top of my head. This means that one of my shaves might equal two of someone that just shaves their face, or even more if they have a thinner beard.

After the first shave, the sharpness increased slightly to 51. This made perfect sense to me as I finish with my goatee area and felt like it wasn’t very sharp when I was ending my shave.

The second shave was actually better than the first. I had a pretty decent shave with no nicks, cuts or irritation, but it did not feel as smooth as many of the other blades that I prefer.

After the second shave the sharpness increased again to 46. What’s interesting, especially based on the first blade I attempted to use, is the fact that there is clearly a very thick coating on the Merkur blades that is being worn away with use and exposing a sharper edge.

Initial Sharpness = 53
Average Sharpness = 50
Edge Retention = 0.87
Smoothness = 3/5

Overall Subjective Rating = 3/5

Platinum Coated. Made in Germany.

When I first released my plan for testing razor blades and that I would be using each blade for 2 shaves, I had a very interesting comment from one person online. They mentioned that 2 shaves (although note this may be 4-6 shaves of just your face) is not enough as some blades take at least a few shaves to “break in”.

To me personally it does not make sense to “get through” a few poor quality shaves when I have many favorite razor blades that I can have one or two great shaves with for 10 – 20 cents. For this reason, I was not a huge fan of the Merkur Razor Blade.

That said, it might do better in a more aggressive razor and based on the consistency I can see why some people might like it. The fact that it is just starting to sharpen up it may suggest the potential of good longevity which may be tested at a later time.

I still recommend everyone try as many blades as you can as your experience may vary, the purpose of this review is to confirm how sharp the Merkur razor blade is relative to other DE razor blades (not very).

Bolzano Superinox Inossidabile Razor Blade

Bolzano Superinox Inossidabile Razor Blade Review

Bolzano. Looks Italian, sounds Italian. I Googled it and Bolzano is a city in Italy. Bolzano Superinox Inossidabile Razor Blades – Made in Germany?!

Well it looks like these were at least once an Italian razor blade and at some point moved the manufacturing to Germany, certainly not the worst country to outsource production to.

Inossidabile translates from Italian as “Stainless”, and Superinox had no direct translation on Google. If I had to wild a guess I would wager that Superinox is an Italian way of saying Super, as in Super Stainless like we see on so many other blades. If that is not correct I am sure someone on the internet will not hesitate to blast me (please comment on this post as well please so we all have the correct answer).

Fresh out of the pack the sharpness measured 52. This is not very sharp, and right there with Derby at 53 (note that Kai was also 53 initially but Kai really sharpened up so this is not a good comparison). Out of about 20 blades tested so far this puts the Bolzano Superinox Inossidabile as one of the 3 least sharp blades out of the package.

For information on what this means check out Razor Blade Sharpness Testing. You can click this link to see a Razor Blade Sharpness Comparison Chart with the other blades tested so far.

Sharpness is only one measure and a lot comes down to smoothness which can be unique to each shaver. As I can usually get one really good shave out of a Derby I was interested to give the Bolzano a try.

Note that I shave my head as well as my face and have a pretty thick growth – except for the top of my head. This means that one of my shaves might equal two of someone that just shaves their face, or even more if they have a thinner beard.

The first shave with the Bolzano Superinox Inossidabile Razor Blade was pretty good other than one issue. I managed to slice myself right above my left ear. It’s interesting that if you talk to a chef or someone that uses knives, they often say you are more likely to cut yourself with a dull blade.

Well it’s been a while since I used a blade that measured in the 50’s and it’s been a while since I cut myself. Just throwing that out there, but I will always take the hit that it could be operator error (ie. me).

After the first shave, the sharpness increased to 46. While this is relatively a typical increase (around 10%) that is seen in many other blades, the sharpness is still in the upper 40’s. I personally like a blade to be in the high 30’s or low 40’s that is also smooth.

The second shave was still pretty good. I was extremely careful in my trouble areas to ensure no cuts which was easily achieved, however this level of attention does always take a little away from my shaving experience. I like to relax and do not feel I should have to focus too hard.

After the second shave the sharpness decreased to 49, which also happens to be the blades average sharpness. The average sharpness is also a tie with Derby, with the only other DE razor blade having a lower sharpness (so far) being the Shark Super Stainless.

Initial Sharpness = 52
Average Sharpness = 49
Edge Retention = 0.94
Smoothness = 4/5

Overall Subjective Rating = 4/5

Titanium Coated. Made in Germany.

Overall I did not mind using the Bolzano Superinox Inossidabile Razor Blade, and although it was not very sharp it was very consistent. I would certainly use it again if I needed to shave, where I would grow a beard before using the Shark Super Stainless again.

As always, your mileage may vary. Personally I will not be purchasing any more of these blades, but it was actually decently smooth and if you like blades that aren’t very sharp then this might be perfect for you.
