Who invented the saw?

A saw is a saw. This was invented by Lu Ban.

Legend has it that the saw was also invented by Lu Ban, but people living in China had already processed and used the tooth stone sickle and clam sickle as early as the Neolithic Age. These are the rudiments of the saw.

Legend has it that once he went into a deep mountain to cut down a tree, he accidentally slipped, and his hand was cut by a leaf of a wild grass, oozing blood. He picked the leaf and touched it gently. It turns out that there are sharp teeth on both sides of the leaf. He scratched the back of the hand with these small teeth, and actually scratched a hole.
