Bill, what is a back bevel?Testing some new edges
It is a compound bevel where the more acute bevel is made secondarily behind an existing edge.Bill, what is a back bevel?
To me back beveling using convex stones mean that i can hone the razor starting from the shoulder of the bevel without the actual apex contacting the stone. I use it as an 2-3 step process, using a different radius on each stone. The first stone shapes the bevel, the second stone refines the lower part of the bevel and starts to work on the apex. The last stone finishes the apex. The last stone can be flat, or have an really big radius (feather light strokes). You end up with a taller, more flexible bevel and a cleaner apex. If you only look at the geometry it does not really make sense, because the radius should not make that much of a difference. The reason you can thin the bevel plane is because it is flexing, if done in a stepwise manner. The effect can be quite dramatic in my opinion. For a more durable edge a flat finisher works just as well and is my preferred way of finishing if the geometry of the razor is good.It is a compound bevel where the more acute bevel is made secondarily behind an existing edge.
When I originally compound beveled knives on rod guided systems I would fully sharpen at say 34° inclusive then redo the very edge on fine grits at 40° inclusive angles. I was later told I should be finishing the knife at the higher angle first, then cutting away behind my edge at the more acute angle. A lot of extra work is involved an I only continue to do it on 1 kitchen knife.
The base theory being, thinner cuts with less force than thick. Thin knives slice carrots easier than thick knives even if they have a duller edge.

Nice shave. Excellent Boker razor. Just finished watching. So your new mount takes you away further from the mirror, not closer?SOTD 12/4/21
