Saw blade
First Claim
1. 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.

Abstract
A reduced resistance saw blade. The saw blade of the present invention has at least two or more groups of sawteeth, the groups of the sawteeth include a first group having a plurality of the sawteeth wherein the tips of the sawteeth are substantially situated on a first imaginary curve which changes in a periodic or irregular cycle, and a second group having a plurality of the sawteeth wherein the tips of the sawteeth are substantially situated on a second imaginary curve parallel to the first imaginary curve. 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.

5. 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, said first imaginary curve having an apex, and a second group comprising a plurality of the sawteeth wherein the tips of the sawteeth are situated so as to describe substantially a second imaginary curve parallel to the first imaginary curve, wherein each group comprises a plurality of sets of teeth, said second imaginary curve having an apex, each set comprising a pattern of a sequence of unset, right set and left set teeth, and wherein further patterns having the same number of teeth reversed in sequence are provided alternately. - View Dependent Claims (6, 7, 8, 9, 10)
