Hi JB,
Thanx for the comments.
On the blade / handle ratio thing. That's an eye thing and not a function thing. Handles are for holding, blades are for cutting. In this design, I wanted a blade that was 3-3/4" long, as I'm planning a larger version. (4-1/4" blade). This is a work knife, not an art knife, so I wanted a handle that was ergonomic for a large hand even with gloves. I guess different designers have different philosophy's behind their designs. The balance and control of the blade to handle has different functions to different designers. Think scalpel. A handle large enough to control the blade and a blade small enough to control and no larger than necessary to do the intended job.
This model took a long time to design and long time to build. Special steel, custom G-10, and we had to assemble twice as we added ceramic ball bearings when we learned the steel ball bearings were rusting.
