Carpenter’s pincers have wide, rounded jaws to help avoid damage to the wood when extracting nails or staples.
The curved shape also lets you rock the pincers from side to side to loosen nails or staples before pulling them out.
Cutting edge
Each cutting edge is bevelled (slanted) to a fairly broad tip. This is because usually you’ll want the pincers to grip, rather than cut, the nail that you’re trying to extract. Having bevelled edges gives extra cutting strength as the jaws are much wider than the tips of the pincers.
If, however, you need to cut the nail or staple off at the base, you can still do this by gripping the pincer handles more tightly and forcing the jaws together.
Pivot point
The pivot point, also called the fulcrum, is the central point around which the handles and jaws of the carpenter’s pincers rotate. It normally comprises a nut or screw.
Handles
The handles act as levers to force the jaws of the carpenter’s pincers together. They vary in length and may be coated in plastic or rubber for extra comfort, or left as bare metal.
