How to use

Install the blade into a compatible Stanley or universal utility knife housing following the knife manufacturer’s instructions for secure fitting. Ensure the cutting edge faces away from your body and lock the blade in the extended position required for the task. Use steady, controlled strokes and allow the blade to perform the cut rather than forcing excessive pressure. Replace the blade when you notice reduced cutting performance or visible wear on the edge.

Recommendations

For safe operation, always wear appropriate hand protection and cut on a stable surface or cutting mat. Keep the blade covered or retracted when not in use and dispose of used blades in a designated sharps or blade disposal container. Choose the correct blade exposure for the material being cut to minimize risk and improve edge life.
