My procedure for testing a Coticule is to hone 3 razors on it and test shave with them:
1. I hone a Double Arrow with the Unicot method. The razor is dulled by rubbing it over a glass object. During the bevel correction stage, I need to undo the double bevel of the previous Unicot. When the razor start shaving my armhair again, I estimate the keeness limit of slurry. For that I have 3 levels: +:shaves my armhair barely, ++:shaves my armhair well, +++ sufficient to shave my face (and get a decent shave out of it).After that, I take it through the taped step of Unicot. After stropping, the razor gets testshaved, usually together with another freshly honed razor, one for each half of my face. The edge is checked for anomalies under the mictroscope, before and after the test shave.
2. I hone a random razor with the Dilucot method. This is mostly a razor that was send to me for the free honing service offered on Coticule.be. All rezors I hone are predulled on glass. Next I correct the bevel, estimate the keeness limit again (note that we're talking about the same Coticule as used for razor1) and take it through dilucot. When the edge passes my standardized HHT, I strop 60linen/60leather and check under the microscope, and put it aside for testshaving.
3. Identical as 2, but with another razor.
I keep notes of all the peculiarities while honing and testshaving. Eventually, I fill in a test form for the tested Coticule, that get's published on Coticule.be
Occasionally, I do an additional a side by side comparison of 2 different Coticules' edges, by honing up two identical razors and test shave with them.
My test shaving procedure is a constant as humanly possible. I won't bore you any further with also elaborating on that.
But I haven't ever thought of creating it on purpose - maybe a few slices through a sheet of paper will do the trick? I wonder if Bart has had any particular procedure for that
