According to "Three Kingdoms. Wu Shu.

The hand saw is cutting when pushed forward, and it can not cut when it is returned backward, so the saw blade should be installed forward when the saw blade is installed; the tension of the saw blade should be appropriate, too tight, it loses its due elasticity, the saw blade is easy to break; Looseness will distort the saw blade, skew the saw seam, and the saw blade will break easily.

Although various automatic and mechanized cutting equipment have been widely used at present, hair saw cutting is still common. It has the characteristics of convenience, simplicity and flexibility. It is used in single-piece small batch production, in temporary construction sites, and cutting special-shaped workpieces, grooving. , Trimming and other occasions are widely used.
