The short article Lu Ban Made a Saw mainly writes about how Lu Ban invented the saw.

During the Spring and Autumn Period and the Warring States Period, there was a creative inventor named Lu Ban in China. For more than two thousand years, his name and stories about him have been passed down among the people, and future generations of woodworkers have honored him as their ancestor.

Lu Ban was born in about 507 B.C. His real name was Gongboban, because "ban" and "ban" sound the same, and he was a native of the state of Lu in the Spring and Autumn and the Warring States Periods, which is why he was called Lu Ban. He was mainly engaged in carpentry. At that time, there was no good way to make trees into flat and smooth boards. Lu Ban paid attention to observation in practice, imitated the biological form, and invented many carpentry tools, such as saws and planes.

Legend has it that once when he went into the deep mountains to cut down the trees, he was careless and slipped, and his hand was cut by the leaves of a kind of weed, oozing out blood, and he took off the blade and gently touched it, and it turned out that there were sharp teeth on both sides of the leaf, and he gently scratched on the back of his hand with these dense teeth, and he actually cut open a slit.

His hand was cut by these small teeth, he also saw a large locust on a weed, two large teeth are arranged on many small teeth, so can quickly grind the blade. Lu Ban was inspired by these two things.

He thought to himself, if such a toothed tool, wouldn't it also be able to saw through trees very quickly! So, after many trials, he finally invented the sharp saw, which greatly improved the work efficiency. Lu Ban gave this newly invented tool a name, called "saw".
