I'm sure I have seen a pen type holder where you can put different type grit stones I'm the end for shaping and rounding work .
Can someone enlighten me on these

Depending upon how aggressive you wan to get, you can also use dowel rod (1/8 or 1/4") of hickory or maple dipped into diamond or carbide abrasive. The wood picks up the abrasive and you can work surfaces quite well. If you are trying to break a square edge, ceramic is the best starting place, and diamond powder on a stick the best finishing place.

That's a great tip thanks
