I have an old Delta water wheel sharpener. It does a hollow gind, but it works. I used it on my old Ranger knives to thin the edge a bit. Nowadays my Kalamazoo belt sander does the work much faster, prettier, and does a convex rather than hollow (concave) edge. Sometimes just thinning the final edge angle a little really improves cutting and chopping performance. No need to do full convex grinds and such unless you have a lot of time and just want one. My only Busse-made full convex blades that I still have are my Busse NMSFNO, Skinny ASH-1, and Sarsquatches. But the NMSFNO and Sarsquatch already had a convex grind to start with, so I really didn't change anything except eliminate the v grind final edges. I just blended the convex grind all the way to the final "zero" edges. Oh yeah, I did do a full convex on the Waki. <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />


Horned, dangerous, and off my medication.
