From Jay Cassell, Field & Stream:
The Gerber Bonecrusher
You know how it’s such a pain to take the legs off a turkey or a goose? Knives don’t work, nor do most saws. The Gerber Bonecrusher is a tool specifically designed to dismember large birds. With rubber composite handles to prevent the clipper from sliding in your hand, this tool applies extreme force with hook-style cutters that won’t slip on the bone while you’re cutting. I just want to know why someone didn’t think of this earlier. $40.
