I'm not offended and I enjoy the riddle. If Buddel had not told me how he made the scales originally I would still be muddling about. Like making a checkerboard end grain cutting board only better....

The screws make sense. What are you using for a pivot pin?

Thanks,

That is some very fancy sawing. If I hadn't read your writeup earlier I would have guessed laser. The scales suit the blade.
