Also provided is a saw blade which includes sets of the sawteeth having reversed set patterns, thus providing a saw blade which is capable of restraining deviation of the cut, maintaining the balance of the lateral sets of the overall saw blade. The saw blade of the present invention includes a plurality of sets of teeth, each set comprising unset, right set and left set teeth, wherein reversed set patterns with the same number of teeth are provided alternately.
A saw blade comprising at least two groups of sawteeth, each sawtooth having a tip, said groups of the sawteeth including a first group comprising a plurality of the sawteeth wherein the tips of the sawteeth are situated so as to describe substantially a first imaginary curve which changes in a cycle of varying amplitude, and a second group comprising a plurality of sawteeth wherein the tips of the sawteeth are situated so as to describe substantially a second imaginary curve substantially parallel to the first imaginary curve.
