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.

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

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.

Derby Extra Razor Blade

Derby Extra Razor Blade Review

Derby Extra razor blades are known to be smooth. In fact, many claim that they are the smoothest blade around. They are not, however, known to be very sharp.

My first experiences with Derby were ok. The great part was that they were a blade that I did not get any irritation, however I did not find them very sharp and with my less than stellar technique I found that they sometimes would pull a bit.

Having completed the review for the legendary sharp Feather razor blade, I figured it would make sense to swing to the other side of the spectrum and give the Derby a spin.

Fresh out of the pack the sharpness measured 53. For information on what this means check out Razor Blade Sharpness Testing. This is pretty well exactly what I was expecting, not even close to as sharp as a Feather (32).

I was very impressed with the first shave using the Derby. It was nothing like what I remembered, it was actually cutting through my 2 days growth no problem. I had an excellent 3 pass shave and no irritation.

After the first shave, the sharpness increased to 44! This is significant and makes perfect sense. As I was finishing my third pass I actually felt like the blade was actually reasonably sharp. I have heard of people liking to get the first shave out of the way, “prime the blade”, etc. and maybe this is why.

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 second shave started off great, but by the time I was near the end I did not feel it was performing anywhere near the first shave. It was still relatively smooth (as in no “scraping” type irritation) but I was needing to put a little more effort into my strokes to move it along.

After the second shave the sharpness measured had dropped back down to 51. I would have like to see how it wears after one more shave, but I am not interested in putting my face through that experience.

Two of my full head shaves are about 4 face shaves, and if you shave every second day that’s a week for about 10 cents. I don’t see why you would want to push this blade any further.

I did not like the inconsistency with the range of sharpness. Starting off not very sharp, then being great, and dropping right down again is less than ideal. That said, for the price I certainly plan to buy more and these will be a use once blade for me that I know I’ll get one great shave and no irritation. I recommend the Derby razor blades for one full head shave or 2-3 face shaves. Also a great blade when starting out.
