Would someone please detail for me how to cut a nail nick? I have used dovetail cutters and they work fine...but you cannot get the very long sweep with one. I know you should probably use a fly cutter or somesuch name with a custom ground cutter. What does this cutter look like and what are correct angles on this cutter? I have a medium size mill so I think I can do it ...but need a little direction. Many thanks.
