Preparation for Blade Replacement Before starting to replace the blade of an art knife, make sure you have a new blade and the necessary tools, such as a clean workspace, safety gloves (optional), and a sharp old blade (if it is one you've used before, handle it safely).

1. Close all possible sources of danger and ensure a safe operating environment. 2. Use safety gloves or handle with care to ensure your fingers do not touch the blade. 3. Locate the locking mechanism of the art knife, which is usually a small button or sliding device next to the blade. 4. Hold the locking mechanism while gently pulling the old blade to release it from the handle. 5. Take out the old blade, being careful not to point the blade towards yourself or others. 6. Open the new blade's packaging and carefully align it with the slot on the handle. 7. Gently press the new blade down until it is fixed in place. Some knives may require a twist or push to ensure the new blade is locked in. 8. Check that the new blade is fully locked and stable on the handle. 9. Finally, perform a light cutting test to ensure that the new blade is working properly. III. Precautions 1. Always maintain concentration during the replacement process to avoid accidental injuries. 2. Do not attempt to repair damaged blades or force dull blades in any way, as this may increase operational risks. 3. Do not allow children or untrained individuals to operate knives. 4. Clean and store the knife promptly after use, ensuring a clean and tidy workspace.
