Lu Ban was the most famous skilled craftsman in ancient my country.
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.
Lu Ban named this newly invented tool "saw".
Another symbol of Lu Ban's invention is the triangle that can draw right angles correctly, also known as Ban Ruler, which tells the craftsman which dimensions are irregular and which ones are according to the rules of divination (feng shui) Unlucky. These rulers are still available in Hong Kong today. Luban attached great importance to the invention of the saw. Or be inspired by a blade of grass with a toothed edge and cut your finger, or see a cricket cutting and eating food with its sharp teeth and leave. Regardless, most are described below. Luban and the craftsmen encountered a task that required them to cut down a large amount of wood. After several days of cutting, they were exhausted and the axes they used were dull. At this time, Lu Ban suddenly cut his finger on a blade of grass. He immediately thought: It would be a good way to make a tool like this to cut wood. He selected a piece of bamboo and used an ax to cut a row of teeth on its edge. The new saw cut through the bark easily, and the soft bamboo teeth wore away quickly as he cut across the tree. However, this proves the principle that sawing can break wood. So Lu Ban put down what he was doing and went to the blacksmith, asking him to prepare an iron plate as hard and sharp as an axe, and then make it into a tooth shape. Luban had this first artificial saw blade, and used it on a wooden roof truss to cut wood accurately and effortlessly.
The final word for this invention was attributed to Lu Ban’s wife. In ancient times, rainy days and hot summers plagued people, and people had to hide under small pavilions instead of going out. There is such a legend that Luban built many small pavilions around his neighbors for everyone to use, but they still did not allow people to go out freely during the stormy season. Lu Ban's wife then made a lightweight bamboo pavilion with oiled paper according to the style of the pavilion built by her husband - of course it was an umbrella. His wife said to Luban: "The house you built cannot be moved. My umbrella can take it everywhere and provide protection in various seasons."
