Thanks all you folks for the kind words here.

I found the series of prototype patterns I made for this knife and one of the drawings. The clear patterns are plexi-glass and are 1:1 scale. The steel pattern is fully hardened and used as a master template to locate both profile and hole centers with. When I do the pre-patterns I use actual size bores so i can make precise hardware sizes on the lathe. This is important for folders.

edited to add, the bottom plastic pattern is Lexan and is my final pattern. Note the never made (yet) clip point blade in the drawing.
