The ancient Greeks and Romans inherited sword saws from the Egyptians.
The Romans also invented a "frame saw", in which a long metal blade was inserted into a wooden frame on three sides.
This kind of saw is generally used for rough machining.
Frame saws can be made very large, usually operated by two people, one on one side of the wood.
Nowadays, frame saws are still widely used to cut logs and log yards.
Modern Egyptian saws are still used by carpenters to do fine work.
Many different types of saws are made for different purposes. The main difference lies in the size and number of teeth.
Large teeth with fewer teeth are suitable for work, and fine-tooth saws are used to cut more smoothly and smoothly.

2. Aircraft
The Ming Dynasty was introduced to China from Rome, which made great contributions to the development of Ming-style furniture.
Before the plane appeared, there was a tool called chisel, which was scraping.
There is no evidence that we ever had a plane. At that time, only scraping, scraping can only deal with cork.
We can scrape the soft ones with a knife, and the hard ones will jump.
The planer was invented in16th century. The planer in China is a push planer, and the planer all over the world is a broach planer.
Saws have a history of two thousand years, and the whole world is similar.
Planes existed in ancient Rome, but they never came in.
On the Riverside Scene at Qingming Festival, large frame furniture appeared, but there were no planes on it.
The application of planer makes furniture advance by leaps and bounds.
Hardwood furniture in China developed rapidly in the late Ming Dynasty, which soon affected the court.
No nation in the world uses this hardwood to make furniture, which is the unique value of China people.
Our hardwood sinks when it enters the water, with a large proportion, very good texture and dark luster like rosewood.
In other dynasties before plane application, hardwood was rarely used as furniture, because leveling was the most difficult thing, so lacquerware was used to cover the unevenness of wood surface.

Hammer is the main striking tool, which consists of a hammer head and a hammer handle. Hammer can be divided into rust removal, nipple hammer, mechanical hammer, claw hammer, inspection hammer, flat-tailed inspection hammer, octagonal hammer, German octagonal hammer and nail hammer according to its functions.
Step 4 chisel
