Hey guys a buddy of mine just gave me some duke leghold traps. one is about 3 inches across with a single long arm and the other is about 4 inches across with the 2 coil springs. I will be trapping coon,fox,coyote,bobcat. I am going to use the dirt hole set up because it does well here. But my question is do these break the animals leg or simply hold it, just curious?
