More questions

Bill Tindall, E.Tn.
I am still trying to decide if I am missing the boat in recognizing some flaw in my approach to sharpening. Why does one need to remove all the concave wear on the area ahead of the cap iron and restore this surface to a perfect plane at each sharpening? I think your picture analysis of the need is flawed. All that needs removing is the rounded tip to restore a sharp edge. If the area behind is concave to the tune of microns why does it matter?

K&K explored searching for a steel that would wear a concave profile on the flat side in a pattern that would self sharpen the tip. They were marginally successful.

Blades are greatly longer than they are thick. Seems to me removing metal from the tip to remove the wear that is necessary to remove is the better choice.
