Chisel

A chisel refers to any of a number of bladed, flat headed carpentry tools, designed to be aligned perpendicular to the cutting direction to cut away material from an object or to cut furrowes into it. Typically it is partnered with a hammer or mallet to achieve the force necessary to drive the blade through the medium. A chisel usually consists of a sharpened metal rod embedded within a wood or rubber handle with a wide base.

The sharp metal end is placed where the cutting is desired, and a hammer striking the blunt handle end drives the chisel into the material (often wood) where cutting is desired.

The tool itself is one of the earliest core woodworking / carpentry tools. But modern chisels have shown a variety of uses.
