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.
