Hi - can anyone suggest the best tool to use for cutting away a corner from a bezel? Most of my books suggest using gravers/scorpers/bullsticks but not the exact shape needed. I have set an uneven square Ocean Jasper cab with sloping sides but I can see it needs fine adjustment at the corners. I filed them down slightly but they really need cutting to make them tidy and I do not possess any of the afore mentioned tools.

Many thanks
Theresa
