I make custom knives, and recently built a two axis (X & Y) grinder to grind the hollowed portion of the blades. Though it seems simple enough, I am not doing as well as I would wish.

I need a program or programs which will enable the grinder to follow the curvature of the lower blade edge and result in a uniform thickness at the cutting edge area.

I think this would be a rather simple task; I have been successful in approximating the desired effect by means of a series of straight tool path moves, but would prefer a more professional and efficient approach.

Any and all ideas and offers would be appreciated. I will of course be willing to pay for the service.
