Jerry is still experimenting to find his signature style for slipjoints. Different techniques for cutting nail nicks. Spotwelded to integral bolsters. Shields. Centering, making the spring flush in 3 positions, dying and jigging bone. He's gotten jigs, patterns, and coaching from Ruple, Tony, Overeynder, Osborne, Elishewitz. And if you think his slipjoints are coming along, you should see his straight knives, lockbacks, and linerlocks. He's been doing those for years and it shows. If I ever buy another linerlock, it will be one of his. Just before I hit the road a week ago, I picked up a Halfrich 4.5 saddlehorn with integral fluted bolster and cap. Thin, sharp, well made. I'll post pictures if I ever get home again.
One thing for sure about Jerry's knives. No matter what pattern or type of knife, it will cut like a scalpel. The geometry and edge are as sharp as anything I've held. If you're not into sharpening, ask him to make it a little more toothy so it will last longer without touching up. If you dont mind touching up an edge, he'll make you a knife that will not only shave or pop hairs, but can split hairs too.
