To obtain a saw which keeps a good cutting property over a long period, can easily cut an object which can hardly be cut by a conventional saw, and is resistant to the adhesion of sap on blade faces in cutting raw wood and capable of smooth cutting and a method for manufacturing the saw.

A saw is formed by a process in which both sides of a saw blade 2 are coated with a surface hardening layer 3, the layer 3 excluding a part of the edge part of the saw blade 2 has a rough surface 5 having minute unevenness, a coat layer 4 is formed on the rough surface 5, and layer 3 is formed on both sides of the saw in which saw teeth are formed in the blade part and the saw body 2, a process in which the edge part 1 of the saw blade 2 of the layer 3 is shielded, a process in which a rough surface having minute unevenness is formed in a part other than the shielded edge part 1, a process in which the shield is removed after the rough surface being formed, a process in which the coat layer 4 for repelling sap is applied on the rough surface 5, a process in which saw teeth 5 are formed in the edge part 1, a process in which the saw teeth are sharpened, and a process in which the saw teeth are subjected to heat treatment.
