How to use

Ensure the utility knife is unloaded and the locking mechanism is disengaged before replacing the blade. Remove the spent blade following the knife manufacturer’s instructions, install the replacement 34 mm blade secure in the holder, and re-engage the lock. Verify the blade is firmly seated and aligned before resuming cutting. Use controlled, even strokes and allow the blade to do the work; avoid excessive force that could damage the edge or the knife.

Usage recommendations

Replace the blade when cutting performance declines, when the edge becomes visibly nicked, or if the blade shows signs of corrosion. Store spare blades in a dry container and handle with care to avoid cuts during changing. For thicker or heavy-duty materials, use a blade and knife rated for tougher applications to maintain safety and prolong blade life.
