Well, maybe I'm overly confident in my abilities to design a knife that I'd like, but that's exactly what I'd do. Having only ground one blade however, I would contract the services of at least one, if not more of the best custom makers out there - after all, cost is no object. It would probably be a folder and would probably look something like a cross between a Strider SnG and a Microtech Terzuola Double Action. I'd probably have Scott Lochsa make the handle on his big machines out of a solid block of titanium, and would then have another maker forge a tough as nails (or, I suppose, considerably tougher) blade.
So nice to dream isn't it?
