What should you do if there is a crack in the middle of the plastic handle of a Swiss Army Knife? There are two treatment methods: large cracks and small cracks.

1. The crack is not big. Use a soldering iron to directly heat the crack in the middle of the plastic handle of the Swiss Army Knife. After the crack is ironed, the gap will not be visible.

2. If the crack is large, use a file to file some foam on the edge of the plastic handle of the Swiss Army Knife, then mix it with glue and add the foam to the cracked seam, and press it firmly with a rope. Wrap it well, let it dry after an hour, and use sandpaper to polish the bonding area.
