EDGE STABILITY IN BUTCHER’S AND KITCHEN KNIVES

[grepper]

You have a good point.  I agree that the test media can roll an edge.  Just cutting through some thin paper once will cause a razor blade to dull.  It’s just those dents that you show seemed excessive.  But then, I’ve never tried sharpening to 8° so the thinness of that edge may account for it.  

Maybe it could be called a SERT (Structural Edge Rolling Tester).
