How to use

Hold the knife with a firm grip and use the slider to extend the blade to the required length for the material being cut. Apply steady pressure and cut away from the body, maintaining a controlled motion for straight, safe cuts. Retract the blade fully into the handle before putting the knife down or storing it. Replace the trapezoid blade when it becomes dull by following the manufacturer’s blade-change steps: ensure the blade is retracted, open the blade compartment or release mechanism, remove the used blade, insert a new trapezoid blade into the carrier, and secure the compartment before use.

Usage recommendations

Wear cut-resistant gloves if working with heavy or slippery materials, and always retract the blade and lock any safety slider before carrying the knife in a pocket or toolbox. Use the minimum blade extension necessary for the task to reduce blade breakage and improve control. Keep replacement trapezoid blades in the original packaging to avoid accidental cuts when handling spares.
