The sawtooth is the core of the saw. Saws with different sawing purposes have different tooth profiles and sawing paths. Generally speaking, the sawtooth shape of the horizontal saw is about 90 degrees, and the sawtooth shape of the vertical saw is about 80 degrees.

Because of the different sawing purposes, the saw has to split the saw teeth into different forms, thus forming a "saw path" with the left and right teeth widened or narrowed. The degree of outward inclination is called "material degree".
