While I'm sure that Jerry keeps prototypes and exemplars of the many different knives that he has made, he would not use them to produce a requested blade. AFAIK, at some point in Jerry's career as a knife designer/maker, he went CNC, (Computer Numerical Control). This means that, with the appropriate computer files and the correct thickness INFI stock , he can cut and "rough out", (for final tempering, grinding and finishing), the blade (or Nuclear Ice Pick) you want.
Actually, you should talk to Garth at the Custom Shop as that's where they make the requested blades. Be forewarned that "Customs", (blades not currently in production) are currently approx. $100 per blade inch and, the last I heard, the waiting period is on the order of two years. Try posting in the "Want to buy" section and haunt the "for Sale" sub-forum and you may get lucky. BTW, this is one of the reasons to go to a show that Busse attends and get up front at the table, as you never know what will be available and the CG models are quite reasonably priced, to boot. Good luck and happy hunting. Pete
