find a good method for sharpening gouges. Almost anything works well for flat chisels and plane blades.
Well, at least we have the easy ones to make us feel like geniuses.
The absolute hardest one for me is my Stubai Sculpture Adze (click). It's an awesome tool for making carving blanks from firewood; then I can use my other tools to turn the blank back into firewood and the circle is complete... Anyway, both ends are a challenge. The ax end is not a flat slope and the edge has a little radius to it (it has a little less now that I have sharpened it a few times) and the gouge end doesn't have a good point of reference that you can pivot on. I have had the most success clamping it in place and using the slipstone and ceramic cone on the gouge end.
