How to use

Slide the blade release to extend the blade to the desired cutting length, ensuring the blade is locked in position before applying pressure.

Replace the blade when it becomes dull by following the manufacturer’s instructions for removing and installing a new standard utility blade.

Usage recommendations

For safe operation, always wear appropriate personal protective equipment such as cut-resistant gloves and eye protection when cutting. Use a sharp blade and replace it promptly to reduce the need for excessive force, which can cause slips. Store the knife with the blade retracted and out of reach of children. Inspect the handle and mechanism regularly for wear and ensure blade retention is secure before each use.
