Now here's a good idea: Machine a saw to cut bone and wood into one end of a piece of AUS-8 stainless steel, and on the other, grind a 4 ¾-inch knife blade with a gut hook. When you press a safety latch and push, one end pivots inside the Zytel handle and the other locks into place. You can't tune a piano with the Revolver, but that's about the extent of its limitations. $87; 888-764-2378; www.sogknives.com
