Unlike standard nail pullers, this forged model is light, compact, and easy to use. With an overall length of just over 8", it fits easily in a toolbox, and can be carried in a tool pouch.
Held and struck like a chisel, it has narrow 4mm (5/32") jaws, which minimize wood damage. The leverage for pulling the nail is provided by your hammer, which can attach to the puller at two points. Sprung jaws stay open until leverage is applied.
Excellent value in a useful tool.
