Step 1: Draw Cutting Lines
Place the foam on a flat table. Use a ruler and pen to draw clear lines according to your design. Fixed lines can help you cut accurately.
Step 2: Preheat the Hot Knife
Plug in the power cord and turn on the hot knife. Wait 15-20 seconds for the blade to heat up fully. Do not touch the blade during preheating to avoid burns.
Step 3: Start Cutting
Hold the tool steadily, let the hot blade follow the drawn lines. Move at a constant slow speed. Do not stop for a long time on one spot, or it will cause excessive melting.

After cutting, turn off the power immediately. Place the knife on a heat-resistant stand and let it cool down completely before storage.
