The newly bought clip needs to be treated, that is, the edges and corners on the edge of the main tooth are smoothed with a knife. This is to prevent the edges and corners from being like knives when clamping prey, and the rabbit's foot suddenly breaks and runs away.
A rotor should be connected between the wire rope tied to the clamp and the clamp. This is to prevent the prey from turning continuously after being caught, and the steel wire will break and run away. This rotor can be made of a 3-inch nail.
