Cutting direction: When cutting, keep the blade perpendicular to the work surface and cut along a straight line or curve. For straight cuts, ensure that the cutting is done in one continuous motion to avoid uneven cuts caused by multiple cuts. 4. Cutting force: Adjust the cutting force based on the material being cut. For harder materials, apply more pressure; for softer materials, cut gently. II. Safety Precautions for Utility Knife 1. Keep clean: Keep the utility knife clean before and after use to avoid rusting or residue affecting the cutting performance. 2. Prevent cuts: Be attentive during use and avoid cutting your hands or other parts of the body. When setting down the utility knife, ensure that the blade is facing down to prevent accidental cuts. 3. Avoid excessive force: Do not apply excessive force during cutting to avoid breaking the blade or damaging the utility knife. 4. Safe storage: Store the utility knife in a safe place when not in use, out of reach of children. Also, avoid placing the knife in damp, high-temperature, or corrosive environments. 5. Regular checks: Regularly check if the blade of the utility knife is loose or damaged, and replace or repair it immediately if there is any abnormality.
