Chisels are designed to be struck on one end, while a sharp beveled edge on the other cuts and shapes materials such as stone, wood or metal. Great tool for doing finish work! Nail sets aid in the fine finishing of projects by allowing a nail to be struck so that it is either flush or below the surface of a wood without marring the wood around it. Another way to use Nail Sets is to leave an indentation in wood for starting screws, which is especially good for hinges and catches.
