Razor Blade Sharpness Testing

Let's talk about single and double edged razors and the blades that they use.

Razor Blade Sharpness Testing

Postby refinedshave » Mon May 15, 2017 11:28 am

Hi Everyone;

It seems we are all very interested in how the sharpness of different DE Razor Blades compare to one another.

I have been working on a site for a bit now which reviews shaving products with a primary focus on Razor Blade Sharpness. With the permission of the forum Admin I would like to introduce refined shave.

Testing is in progress to test all DE razor blades and publish values for new, and after 1 and 2 shaves. Please follow this link to learn more:

Sounds interesting. I might sign up for the results. There are so many brands of blades current and past that I imagine it is/will be a daunting task to round them all up. Is sharpness the only criteria? Are you also looking into such inherent blade characteristics as longevity of the edge, cost per blade, availability, smoothness, harshness, rusting, country of origin, etc.?

This can only be objectively tested in a controlled laboratory setting using advanced calibrated eqpmt. Anything less is merely subjective conjecture & therefore meaningless other than a crude barometer for a neophyte.

Interesting and worth a try. You might take a look at Squire's thread that shows some magnified images of the blade grind/ hone. Oddly I usually find the Feathers are at their best for shaves 2-5 then they start to dull. The first shave is rarely the best with a Feather IMO.

There certainly are a lot of blades, I have 40 for now and will go from there. Sharpness is the main criteria as it can be measured. I will also be doing a full review on each blade regarding the personal performance, however things like smoothness will be subjective to each shaver so my comments on this will be more of a for your information.

Initially the testing will all be 2 full head and face shaves per blade, but as I am going I am seeing that some of the blades will be interesting to do some endurance testing to see how long they can keep their edge, and then that is where things like monitoring oxidation (rusting) would come in.

Hope you sign up and thank you for the interest!

Did you check out the website? I purchased calibrated equipment. The scale is designed specifically for sharpness testing and I am using calibrated test strips for each test. A jig has also been manufactured to mitigate all the other variables such as bending, angle of cutting etc.

I have a background in Materials Engineering and graduated with honors, I have my share of laboratory experience. I'm not sure how advanced you would require to meet your standards, but I am confident that the current set up will provide results that will satisfy the curiosity of the majority of wet shavers.

Thanks for the tip! Your comments about Feather are interesting as they are right in line with the review. I noticed an immediate drop in sharpness for the Feather and then very consistent after the first and second shave. I shave my full head and face so I would say my 2 shaves is about 4 regular face shaves. Thanks for the interest!

I have subscribed. I added a shortcut to my desktop. Your website is impressive. I hope several of the SMF gents will visit so they can get a good idea of what you are providing to the wet shaving community. Today I already learned something new, and that is that MWF makes a good hand and body lotion, even though they don't offer an "aftershave". I'm looking forward to following along as you continue the process. Thanks!
