Straight Razor Honing Hone Shaping Lapping Plate - Allows a Concave Razor Bevel

Description

This ~9x11x0.5" (0.5" = maximum thickness at corners) CNC-milled aluminum plate holds sandpaper to form whetstones specifically to the task of honing razors.
You get access to two reference shapes for your hones; a short-diameter, thick-second-diameter shape for bevel-setting (face stone to 9" axis for this), and a long/narrow shape for finishing (face 11" axis with hone).
A concave abrasive field produces a durable convex cutting edge (found upon axes and othertools for rough conditions), inappropriate for shaving.    The cutting edge isn't flexible and is intended to be stiff for the tasks an axe or other rough cutting tool regularly encounters.
A flat abrasive field produces a V-shaped flat (isosceles triangle) cutting edge - less durable than a convex and more durable than a concave edge, and appropriate (but not ideal) for shaving.  Its shape is neutral in regards to influencing flexibility.
A *convex* abrasive field produces a *concave* edge, more fragile than a flat (vee-shaped) or convex edge, materially thinner, with a reduced edge radius and a reduced effective cutting angle.
Much more important, however, is its thinner bevel profile, which causesa more flexible cutting edge
.   Just as various "canopies" of a shaving brush head affect its backbone, shaping bevels affects flexibility.
As you can see from any shaving forum discussion and from the one particular picture in this listing resembling a common human organ, the open discussing of this concept in the internet age upon any straight-razor-centric forum will cause a dedicated cabal of those threatened by its notion [steve56, gssixgun, euclid440, daltongang, twelvefret, buca3152, etc.] to stop at nothing to ensure the information is squelched/scuttled.   They're pathetic, frankly.   Their main worry is that you know they've been around a long time on the forums and they're ashamed all that time they didn't know about this old advantage.
