ciladog - Thats interesting I never thought of that, it probably gives a better grip if you work up on the blade as well.
On a side note, I use some big heavy choppers that I've made rough (most of my blades..) and when chopping down trees and bushes the bark tends to get into the depressions. A wire brush will get it out.
On another side note, this thread got me thinking. I have been lazy sometimes and rushed a knife, usually the heat treat comes out sub par. And I get excessive scale forming on the blade because I crank my blower too fast. So yesterday I forged a small blade and kept it clean from scale and took my time during heats. Though its not the largest blade I have ever made, it has been 98% forged to shape and carefully heat treated. I even took extra time working the handle, I reckon it took me twice as long to make it than it usually would start to finish.
I'm saying I learned from this thread, the knife had no scale to clean off; no major pits or hammer marks. Holds a good shaving edge even after whittling for a while on oak. It does sport a nice forge finish.. Which I'm fond of, a true carry around advertising knife.
