When using hook blades, due to their special shape and relatively sharp blade edge, a series of precautions need to be followed to ensure safe and effective use.
1. Safety protection and basic operating specifications
Personal protective equipment
Before using a hook blade, be sure to wear appropriate personal protective equipment. For example, protective gloves should be worn to prevent accidental scratches on the hands during operation. When cutting some hard or unpredictable materials, such as metal wires or hard plastics, the materials may suddenly break or splash, and protective gloves can provide some protection.
At the same time, goggles are also very necessary, especially when performing operations such as cutting carpets and cloths that are prone to fiber debris, these debris may enter the eyes and cause injury. Goggles can effectively block debris and ensure eye safety during operation.
Correct holding method
The knife should be held correctly and steadily. When holding a hook blade, you should hold the handle naturally with your fingers, and keep your hand relaxed but firmly controlled. Avoid over-gripping or unstable grip. Over-gripping may cause hand fatigue during use, while unstable grip can easily cause accidental cutting.
For example, when using a hook blade to strip wires, if the grip is unstable, the blade may deviate from the intended cutting route, which will not only damage the wire, but may also cause harm to the user.
Avoid accidental injury to others
When using a hook blade, always pay attention to the people around you. Make sure the direction of the blade is away from others to avoid accidentally injuring others when swinging or cutting.
In a multi-person work environment or family scene, if you use a hook blade to cut with other people around, even a small swing of the blade may cause unexpected harm, so be extra careful.
2. Points to note for the characteristics of hook blades
Cutting direction and force
Since the hook blade is suitable for pulling and cutting, this feature should be followed during the cutting process. When cutting the material, try to apply force in the pulling direction instead of forcing the push cutting, because the shape of the hook blade will hinder the push cutting, which is not only inefficient, but may also damage the blade or fail to effectively cut the material at all.
For example, when cutting textiles, after fixing the material, use the hook blade to start from the edge and pull away from yourself, so as to ensure the smoothness of the cutting and the neatness of the material cut.
Use and protection of hooks
When there is an opportunity to use the hook function of the hook blade, such as hooking the rope or the edge of the cloth, pay attention to the strength of the hook. Do not pull too hard to avoid deformation or damage to the hook.
After completing the hook-pull operation, if there are some fibers or debris left on the hook, clean it up in time to prevent the debris from affecting the next hook-pull operation or causing corrosion and other damage to the blade.
3. Inspection and maintenance of the knife
Inspection before use
Before using the hook blade each time, check the knife. Check whether the blade is damaged, such as whether there is a gap on the blade, whether the blade is rolled, etc. If the blade is damaged, the blade should be replaced or repaired in time to ensure the cutting effect and safety.
At the same time, check whether the handle is firm. The loose handle during use may cause the blade to be unstable during cutting, which may cause dangerous situations.
Maintenance after use
After use, clean the hook blade in time. If you have cut sticky materials such as tape or ropes containing grease, wipe the blade and hook part with an appropriate solvent to remove residual impurities.
The blade also needs to be treated with moisture-proof treatment to prevent rust. You can store the knife in a dry and ventilated place, or use a special knife anti-rust oil to apply to the blade for protection.
