Saw, this seemingly ordinary tool, plays an indispensable role in the development of human civilization. Its origin can be traced back to the Stone Age, and with the continuous development of human production and life, saws have also undergone a series of complex and interesting evolution processes. In the distant Stone Age, people used the natural shape and texture of stones to make simple saws. They choose hard stones, sharpen their edges, and use them to cut animal skins, wood, and other natural materials. This primitive saw design was simple, but very practical, opening the way for humans to use tools for cutting. With the mastery and utilization of metal by humans, saws have also begun to be made using metal materials. The emergence of metals such as copper, iron, and steel has made saws more durable and precise. In China, ancient saws were made of bronze or iron, with various shapes, some resembling birds and some resembling fish. The design and manufacturing of these saws reflect the cultural and technological level of the time. In Europe, people began using hacksaws during the Middle Ages. The emergence of hacksaws has improved the efficiency and accuracy of cutting. At the same time, the design of saws has become more complex, including handles, blades, and blade fixing devices. The design and manufacturing technology of this hacksaw gradually spread to various parts of the world, becoming the main tool for people to carry out cutting operations at that time. Entering modern society, with the arrival of the Industrial Revolution, the design and manufacturing…
Electric saws are a widely used tool, and their powerful power and diverse applications make them irreplaceable in various industries and scenarios. There are various types of electric saws depending on the usage environment and purpose.

The saw blade of a band saw is in a strip shape and can be used to cut wider materials, such as wooden boards or metal plates. Chain saw is an electric saw that uses a chain as the saw blade, with strong cutting force and is mainly used to cut hard materials, such as stones or concrete. Rail type electric saw Rail type electric saw is a tool particularly suitable for large-scale wood cutting. Its saw blade is installed on a track and can slide freely along the track, thus achieving linear cutting of large wood. This type of electric saw has high cutting accuracy and is easy to operate, making it an important tool in industries such as construction…
