2. Lu Ban invented the "saw"

One day, Lu Ban went to a high mountain to look for wood. Suddenly his foot slipped and he hurriedly reached out to grab a clump of thatch beside the road. My hand was torn by thatch and blood oozed from it.

"Why is this humble thatch so sharp?" He forgot about the pain of the wound, picked up a handful of thatch and looked at it carefully, and found that there were many sharp teeth on the edges of the grass leaves. He used these dense teeth to lightly scratch the back of his hand, and actually made a gash.

He thought: If I also use a tool with many small saw teeth to saw trees, wouldn’t I be able to saw the wood quickly? That would definitely take less effort than chopping with an axe.

So, Lu Ban asked a blacksmith to make dozens of iron pieces with sharp small serrations on the edges, and took them to the mountain for experiments. Sure enough, the trees were soon cut down.

Luban gave this newly invented tool a name, called "saw".

Human inventions - inspiration from animals Boats and submarines come from people's imitation of fish and dolphins. Scientists made the world's first gas masks based on the unique ability of the fire boar's nose to detect poison. The rocket takes off using the recoil principle of jellyfish and cuttlefish. By studying the color-changing ability of chameleons, scientific researchers have developed a lot of military camouflage equipment for the troops. Scientists studied frog eyes and invented electronic frog eyes. The U.S. Air Force researched and developed a miniature thermal sensor through the Viper's "heat eye" function. Humans also designed the toad ram (hang) using the principle of leaping frog. Humans imitate the highly sensitive sense of smell of police dogs to create "electronic police dogs" for detection.
