I have two suggestions:
First: any tool of the woodturning crafts
Second: A tool that helps you sharpening chisels or similar tools (like plane...) you put it between the two jaws (if that's the right word...) and then go to your sharpening maschine. it's difficult for me to explain in english, but something similiar i'm using
Welcome Markussw, I know of the tool you speak of. I used one when I was in school learning to do the work with wood.
Not the right answer I'm looking for.
Monday I will give the correct answer.
