    摘要： A hand-operated implement has a guide bar on which is fitted a cutting chain for cutting mineral and metal materials. The cutting chain is driven around the guide bar by a chain sprocket. The chain sprocket is arranged in a chain sprocket chamber which is delimited by a chain sprocket cover. A cutting element has an outer side facing a sidewall of the chain sprocket cover which lies in a first notional plane. The distance between the sidewall and the first notional plane measured perpendicular to the first notional plane and centrally between the top of the cutting element and the peripheral wall is less than approximately 0.8 cm over at least 30% of the section between a second notional plane containing the central axis of a fixing bolt on the guide bar and the exit opening at which the cutting chain leaves the chain sprocket chamber.

    摘要： A saw chain which is reversible having adjacent chain sections each having a pair of cutting links with cutting teeth disposed on opposite sides of the chain having flanged cutting teeth extending over the chain. The cutting edge on the pairs of cutting teeth on adjacent sections are oppositely disposed so that when the chain becomes dulled it can be reversed on the chain saw bar to reverse the chain sections to place sharp teeth in the cutting position and the previously used teeth are in a non-cutting position.

    摘要： A saw tooth, of which a number are removably mounted on a tree-felling saw head, includes a body portion having a lead cutter and a trailing primary cutter separated by a throat. The combined lead cutters function to cut a narrow side wall kerf on each side of a larger principal kerf together with corresponding inside corners of the larger kerf. The remainder of the larger kerf is then cut out by the following primary cutters, forming a square cut end. As the cut progresses, the combined primary cutters separate the longitudinal fibers of the tree at the square cut end without double cutting the fibers, thereby improving cutting efficiency and reducing energy requirements in felling a tree.
