An easy & economical method is to use several grades of wet/dry emory paper from 220-320-400-600-and higher grits glued to a thin foam mousepad to shape the bevels of a Scandi. I have never felt the need for the mousepad, but others swear by it.
Practically, I have never needed to give any of my Scandi grinds a full resharpening as I typically will leather strop them after use to bring out a scary sharp edge.
