Abstract
A lightweight disposable cutting chain for use with small, compact power supplies comprises in one embodiment a series of links formed of wire. On certain links an end of the wire loop forming the link is cut to form a sharp edge capable of shaving material, such as wood, being cut. The links are arranged so that a narrow kerf is first cut by the links, other links being formed with cutting edges to shave material and widen the kerf. In other embodiments some or all of the links comprise metal plates formed by stamping from sheet metal.
