Did this project ever go live?
Did you find a fixed blade?
While not specifically a fighting knife, I like my SEAX as a one knife solution to most questions.
Its handle shape allows a variety of grip styles, protects your hand from over running the blade, and is friendly in nature. The SEAX blade shape is very functional. Its point is centered and thick enough for light prying but pointed enough for starting a thrust cut. The edge is straight enough to get full use out of the cut, whether near the tip, belly or rear of the blade. It is a well proportioned knife that never feels like the blade has more leverage than the handle.
When you consider that a lot of fighting knife designs are pretty worthless for anything else, the SEAX shines as a GP knife that can cut its way out of trouble. And it does not matter if the trouble is a tough steak, a line entanglment, or that guy that won't take "Fuck Off" for an answer.
Zion Forge also has some good designs with some flexibility in options. I think you get a discount if you can pronounce his name right, but most folks just call him Majic. The guy knows how to run a knife too.
