There was a recent thread on engraving cutters on one of the lists, but I can't seem to find it now, and I don't think it actually had an answer to suppliers of ready ground engraver tools?
I'm looking in particular for a 20 degree cutter that matches the narrow dremel V cutter but has an actual point and a matching 0.5mm tip for getting cleaner cut results from vcarve. I'm getting nice detail, but the result is spoilt by the burrs from the dremel tool :(
