Title: It's a Grind, but It Does the Job
Review: I use these with a hand jig attached to my dremel tool for sharpening the teeth on my 16" chain saw. The stone material is good for about 7 or 8 uses, depending on how aggressive I am in sharpening. I find these to work much better than the diamond studded shafts which lose their effectiveness (diamond dust comes off) after one or two uses.
