I have two honing "sticks/paddles," I think one purple and one green, no idea what the grits might be. Purple doesn't seem to remove metal fast enough to be practical, the green feels very coarse in use as if leaving scratches. Also have a found metal honing plate, likely diamond, that also doesn't seem to remove metal fast enough to be practical. So I'm wondering what "grit" honing devices other use to touch up the cutting edge on bowl gouges. I understand very well the technique, and get narrow shiny lines at cutting edge and heel (hollow grind) but don't see improvement in the surface.
