Nail remover is a tool used to remove nails from wood or other materials. The term can refer to three different tools: a CLAW, a peen, and a clawhammer. A CLAW is a type of tool with two curved metal arms that can be used to pull out nails. A peen is a type of hammer with a flat head on one side and a pointed end on the other, which can be used to pry nails out of wood. Finally, a clawhammer is a type of hammer with a curved CLAW at one end, which can be used to pull out nails. All three tools are used to remove nails from wood or other materials.
