I think this will be both first and last time that I try and change the knot in a handle that is epoxied in. I have a nice jungle acrylic handle that I stopped using because I did not like the knot. I got a different knot and proceeded to try drill the old knot out. I was able to drill out the center of the glue bump with a spade bit, but trying to get the remaining glue bump out with a rotary tool has been impossible and I've already damaged the rim of the handle quite a bit. I'd still use it if I could figure out how to cut the rest of that glue out. Anyone use a dremel for this and can tell me what kind of bit to get? Any help is appreciated.
