"Why is this simple thatch so sharp?" He forgot the pain of the wound, pulled up a thatch and studied it carefully. He found many small sharp teeth on the edge of the grass. He scratched the back of the hand with these small, dense teeth and even scratched a hole.
He thought, if I saw the tree with a tool with many small serrations, wouldn't I be able to see the wood soon? That must be much easier than chopping with an axe.
Therefore, Lu Ban asked the blacksmith to make dozens of iron pieces with sharp serrated edges and take them to the mountains for experiments. Sure enough, the tree was soon sawed off.
Lu Ban named this newly invented tool "Saw".

4. The story of Luban sawing. It is said that the woodworking saw was invented by Lu Ban.
Once, Luban built a palace and needed a lot of big wood, so he told his disciples to go up the mountain and cut down trees. At that time, there were no saws, and all the trees were cut with axes, so few trees could be cut in one day.
Luban was in a hurry, so he went up the mountain to see it himself. The mountain was steep, and Lu Ban grabbed the roots and weeds and climbed up step by step.
His finger was suddenly cut by grass and he was bleeding. How can a grass have such a history? When Lu Ban looked carefully, he found that there were many small teeth on the leaves of grass.
He tried to pull a hole in his finger, which reminded Lu Ban. He thought, if you hit a toothed tool with iron and pull it back and forth on the tree like a blade of grass, wouldn't it be much better than chopping down a tree with an axe? He immediately went back to play and took it to the mountain to try it. It is faster and easier than an axe.
That's how Lu Ban invented the saw. I hope it will help you and be adopted. Your adoption will be our motivation to answer questions.
