一、Production description： 

The double-edged hand saw achieves the purpose of cutting by manually pulling the saw blade so that the saw teeth interact with the material being cut. When the saw blade is pulled forward, the saw teeth cut into the material and gradually cut the material. Since the saw blade has two cutting edges, it can cut in different directions, which improves work efficiency.

二、use： 

1：Generally, it is made of high-quality steel and has sharp teeth. The length and width of the saw blade can be selected according to different usage requirements.

2：Unlike traditional single-edged hand saws, double-edged hand saws have two cutting edges that can cut in different directions, improving work efficiency and flexibility.

3：The teeth on the saw blades are carefully designed and sharpened, evenly spaced, and can cut a variety of materials quickly and smoothly. Different saw tooth shapes and sizes are suitable for different materials and cutting needs.

三、Performance has advantages：

1: A double-edged hand saw has teeth on both sides, one side has teeth suitable for horizontal sawing, and the other side has teeth suitable for vertical sawing.

2: It can not only saw wood, but also has good sawing effect on some plastics, rubber and other materials, and has a wide range of applicability.

3: Saw blades are usually made of high-strength steel or alloy materials, have high hardness and toughness, can resist the wear and impact generated during the sawing process, are not easy to deform or damage, and ensure the service life of the saw.

四、Process characteristics

(1)The teeth of a double-edged hand saw are usually specially designed and processed to improve sawing efficiency and quality.

(2)The material of the saw blade is usually high-strength steel or alloy material to ensure the hardness and toughness of the saw blade.

(3)The manufacturing process of a double-edged hand saw is usually quite delicate and requires multiple steps to complete.

(4)In order to improve the safety of use, double-edged hand saws usually adopt some safety designs, such as saw blade guards, safety locking devices, etc.
