Abstract: A saw chain made according to the present invention includes cutter teeth having a single slicer. Sequentially, the cutter tooth having a slicer on the left-hand side is followed by a raker tooth having an open face on the left-hand side. A cutter tooth having a single slicer on the right-hand side is followed by a raker tooth having an open face on the right-hand side. The wood is cut sequentially by the left-hand slicer, the raker tooth having an open face on the left-hand side, the right-hand slicer and the raker tooth having an open face on the right-hand side. The particular sequence of cutting provides a fast and smooth cut that avoids binding in the kerf. Alternatively, the cutter tooth having a single slicer on the left-hand side may sequentially follow a cutter tooth have a single slicer on the right-hand side. A raker tooth having a full-width raker may follow the sequential cutter teeth or two raker teeth having respective half-width rakers may follow.

Abstract: A side cutter tooth includes an element having a tip which extends upwardly substantially parallel to the plane of the body. Improved performance is achieved by designing the inner surface of the cutter tip to reduce "clearance" or to create "interference."A single-element side cutter tooth for scoring only one side of a kerf is also described.

Abstract: A side cutter tooth 10 or other chain saw tooth includes a tip 36 which extends upwardly substantially parallel to the plane of the body 24 or which is inclined inwardly at an angle of 0.degree.-50.degree. towards the angle of the body 24 to create improved resistance to crimping and breakage of the cutter element 34 of the tooth 10 so that the tooth will not deflect outwardly when exposed to a downward force, such as often experienced during a bind or pitch. Protection of the tooth 10 is also provided by including at least one corrugation 42 in the vincinty of the curl outwardly from the body 24 to reinforce this curl and to further reduce crimping and breakage. That is, the corrugation 42 includes a stamped portion of the link 20 or 22 spanning the intersection of the cutter element 34 with the body 24.
