How to use

Slide the blade out using the knife's retracting slider or mechanism until the required blade length is exposed. Hold the handle firmly with a comfortable grip and position the blade against the material to be cut. Use steady, controlled strokes while maintaining even pressure; avoid twisting the blade. After use, fully retract the blade into the handle to reduce exposure. Replace the blade when it becomes dull by following the manufacturer’s blade-replacement procedure: ensure the blade is retracted and the tool is secured, open the blade housing if required, remove the used blade, insert a new trapezoid blade, and reassemble according to the tool’s design.

Usage recommendations

Always keep the blade retracted when not in use and store the knife out of reach of children. Use appropriate personal protective equipment such as cut-resistant gloves when performing repetitive or forceful cutting tasks. Replace blades promptly when they show signs of wear to maintain cutting efficiency and reduce the need for excessive force.
