Check out my site for exotic wood grips, as well as other materials, such as stag, micarta, etc. I can also do almost any kind of custom work that you would want. You may want to furnish your own wood or material.
I am also interested in teaching the art of making grips. The teaching is free, I do not charge for this service. All you have to do is ASK. Everything I do is old school, not CNC.
