Product Use and Maintenance Instructions:

1. For new folding knives: If the blade fails to lock, please open the knife repeatedly using firm force or a flicking motion. Because the locking mechanism on a new knife fits very tightly, insufficient force during opening can prevent the blade from locking properly.

2. After the knife has been used for a period of time, please check the screws regularly. If they become loose, tighten them promptly; otherwise, the blade may fail to lock.

3. With prolonged use, please apply a small amount of lubricating oil to the pivot point (where the blade rotates) to ensure smooth opening and closing.

The folding knife weighs 210 grams and is made of pure metal. Please consider this before purchasing.
