Razor Blade Sharpness Chart

Interesting but a bit pointless really.
I like knives and other sharp things and mostly I sharpen my own; axe, machete, penknife, cook's knife, paring knife whatever they are all different. Without knowing the relative hardness of the edges and the angle of the edge and how that relates to the angle of use, nevermind what treatments have been applied what does that test show?

After you pony up the cash for this machine I will gladly supply you with that your heart desires:

:D ;)
 
This testing confirms a lot of my conlcusions and some "common truths" out there i.e. Feather is very very sharp and drastically looses sharpnes after each shave, Rockwell razors blades are the dullest and so on.

Which will result in the same sort of data set so ...why?
I had to teach my daughter how to use a knife to carve wood and not blunt her knife in minutes i.e. cut at an angle not perpendicular to the surface - or use a blade with a less acute edge.
 
If you read all of his blade reviews things (at least for me) fall perfectly into place per my experiences. The Feather is the sharpest initially at his score of 32 (lower being sharper) and the closest is the Nacet Stainless at 39 which for the latter makes sense as it's marketed in the Middle East where men are more hirsute on the whole. The real surprise for me is the Bic Chromium Platinum which starts at 40 & then drops to 33 after the first shave and then 32 after two shaves. This however makes perfect sense as many say (including myself) it shaves rough after the first shave which is because it's getting sharper as the coating quickly wears away sooner than almost all other blades it appears. The price to pay for initially being too sharp (or a poorer coating?) for the Feather is a rapid "death".

The takeaway is that the blades that most gravitate to are the ones that are consistent and are a veritable balancing act between sharpness & smoothness with no small part due to the longevity of coating as it wears down. There is pure genius in the simplicity of his rating system that just flat out makes sense to this reader.

I Can Have these Blades Anywhere I Want them as I Hone My Own..These Don't Dull Like Factory Blades as they Get Maintained Between Shaves..No MAGIC COATING..Just Pure Swedish Carbon Steel..The Best..I Will Never Put a Factory Blade Near My Coupon Again..;)

Factory Blades are Barbaric Compared to these Full Hollow Grinds..:D:D

I think you are on the right track. When I used to make wooden furniture all my chisels and hand plane blades were made out of high-carbon steel. I sharpened them on a thick piece of float glass and used 3 to 4 grades of metal type sand paper: starting with a low number grade and ending up with 1200 grade. High-carbon steel can be made very sharp but is pretty brittle. I have never seen good hand tools made of stainless steel and every artisan I knew always hand sharpened their tools. Some used sharpening stones with oil and others used the float glass/sand paper method.

Years ago, the head of Gillette's R&D during the "Golden Age" stated on record that their carbon Blue Blade was their sharpest blade ahead of their stainless ones. I have a few of late production (1976) carbon Blue Blades that are silicone coated and they shave like a dream. They make the Treet "Black Beauty" seem like shaving with a washboard. I would bet dollars to dog turds that if Gillette made a limited run of these today using current coating/sputtering technology that they would sell faster than doobies at a Bob Marley concert. ;)
