How to use

Install the blade into a compatible utility knife following the knife manufacturer’s blade-change instructions, making sure the blade is properly seated and secured before use.

Replace the blade when you notice reduced cutting performance or visible bluntness to maintain safety and cut quality. Store spare blades in their original packaging or a safe container to avoid accidental contact.

Usage recommendations

For safer operation, wear appropriate hand protection and cut away from your body. Use the 18 mm Stanley blade for tasks requiring precision rather than heavy demolition; select a wider or specialized blade for thicker or reinforced materials. Dispose of used blades in a dedicated blade-safe container to prevent injury.
