How to use

Hold the knife with a firm, controlled grip and align the blade with the cutting line. For deep cuts, use several light passes rather than a single heavy stroke to improve precision and reduce blade stress. To change the blade, follow the built-in replacement procedure: ensure the tool is secured, remove the spent blade according to the knife's mechanism, and insert a new compatible blade until it locks in place. Store spare blades safely and retract or cover the blade when the tool is not in use.

Usage recommendations

Use personal protective equipment such as safety gloves and eye protection when cutting. Match blade condition to the task: replace blades when they show dulling or chipping to maintain clean cuts. Avoid using the knife on materials or in applications that require specialized or hardened blades to prevent premature wear of the 3Cr13 blade.
