What are the dremmel attachments, if any, that work for notching or rounding a corner on cheap steel. I got a years old "rough use" knife from CTD. All I know is that it's stamped Fury and China and will take almost any punishment I dish out and keep a decent edge (once I put one on there). However, the grip area is a tad too small for my hands and I would like to make a few tweaks. However, since I'm apartment bound (no tool shop) and cash poor (not gonna invest in any big toy) I wanted to see what my sorry old dremmel might accomplish but I don't want to burn it up trying the impossible. Hence the question--what kinda dremmel bit will do the job if it can be done?
