Probably not well. It is designed to cut round stuff. A ratchet cutter
like that with a flat platten might work but I just use heavy duty
kitchen shears for stuff like that. Never did a turkey but they cut up
a chicken like butter.
I do like the Julia Child trick of cutting off the ends of the
drumsticks right where the meat starts before you cook it. Then the
tendons will be poking out and you can pull them right out of there
while you are letting the cooked bird rest. A PVC cutter is perfect
for that.
I've never heard of that idea. Will check it out. Now I may have to get a PVC
cutter, although I suppose a bolt cutter would work for a turkey leg - unless
it's a 40lb'er.
