1. Ensure Safety: Before using the utility knife, make sure the work area is safe and out of reach of children and other unrelated personnel. Wear appropriate work clothes and gloves to prevent accidental cuts. 2. Prepare Tools: Select a suitable utility knife based on your needs and ensure the blade is sharp. Check for any damage or bending of the blade and replace it if necessary. 3. Usage Method: When holding the utility knife, fix the handle with your thumb and index finger, and point the blade towards the work area. Keep the blade perpendicular to the work surface during cutting, applying even and steady force. 4. Cutting Materials: Choose the appropriate cutting method based on the material to be cut. For harder materials, test the blade's sharpness in a non-essential area first. Avoid sawing back and forth or applying excessive force during cutting to prevent damage to the blade or workpiece. 5. Keep Clean: Clean the utility knife promptly after use to maintain the hygiene of the blade and handle. Use a soft cloth to wipe the blade and handle part, ensuring there is no dust or oil contamination. II. Precautions 1. Prevent Injuries: Stay focused when using the utility knife and avoid being distracted or talking to others. During operation, keep your fingers or other objects away from the blade to prevent accidents. 2. Avoid Excessive Force: Avoid applying excessive pressure on the blade during cutting to prevent deformation or breakage of the blade. 3. Safe Storage: When not in use, store the utility knife in a safe place out of reach of children. Do not place the utility knife near flammable materials to avoid danger. 4. Regular Checks: Regularly check the blade of the utility knife for sharpness, damage, or bending. Replace the blade or the entire utility knife if there is any abnormal condition. 5. Proper Waste Disposal: Used utility knives and discarded blades should be disposed of properly to avoid environmental pollution.
