Always keep the blade sharp: Using a sharp blade can reduce resistance during cutting, make cutting smoother, and also reduce accidental injuries caused by blunt blades.
Avoid excessive force: When using a utility knife, avoid excessive pressure or forced cutting. Excessive force not only easily damages the blade, but may also cause the blade to suddenly break or pop out, causing injury.
Cut in the correct direction: When cutting materials, always push the blade away from your body. This can avoid cutting yourself with the blade due to a slip during the cutting process.
Pay attention to the cutting environment: When using a utility knife, make sure the cutting environment is safe and free of debris. Avoid working on unstable or sliding surfaces to prevent accidental slips or bumps.
Don't point the blade at people: No matter when or where, the blade of a utility knife should not be pointed at yourself or others. Even if the blade is worn or damaged, it should be properly handled to avoid accidental injuries.
Be careful when storing: When the utility knife is not in use, it should be stored in a safe place away from children and pets. Also, make sure the blade's protective sheath is reinstalled to prevent the blade from being exposed and causing injury.
