一、Production description： 

Saw blades are generally made of high-quality steel, with high hardness and sharpness, and can effectively cut wood, plastic, rubber and other materials. The handle is usually made of plastic, rubber or wood, and the design conforms to ergonomic principles, providing a comfortable grip and allowing users to better control the saw during operation.

二、use： 

1：During the sawing process, keep the saw blade vertical and stable, and avoid shaking or tilting left and right to avoid affecting the sawing efficiency and quality.

2：During the sawing process, you can judge the sawing depth by observing the position of the saw blade and the changes in the material, and adjust the sawing force and direction in time.

3：The saw blade and single hook can be coated with lubricating oil or rust inhibitor to prevent rust and wear.

三、Performance has advantages：

1：The connection between the saw blade and the handle is firm and reliable, and can withstand large cutting forces without loosening or shaking.

2：Due to the portability and cutting ability of the single hook waist saw, it also plays an important role in emergency rescue.

3：The design of the single hook waist saw is also very user-friendly. The shape and size of the handle are in line with ergonomic principles, making it very comfortable and convenient to use.

四、Process characteristics

（1）The sawtooth shape is carefully designed, and common ones include alternating helical teeth, wavy teeth, etc.

（2）The connection between the saw blade and the handle is usually made by high-strength rivets, screws or welding.

（3）The surface of the single hook may be treated with zinc plating, chrome plating, etc. to improve its corrosion resistance and aesthetics.

（4）During the assembly process, the dimensional accuracy and assembly accuracy of each component will be strictly controlled to ensure that the saw blade, handle and single hook fit tightly and firmly.
