Cutter knife 18 mm, with blade fixator

This 18 mm utility knife with a blade lock has a wide, solid blade for thick cardboard, tape, stretch film and bubble wrap. The lock holds the blade in place so it doesn't slide back into the handle when you cut 5-layer board. The blade is scored into segments, so when the tip goes dull you snap one off and carry on with a sharp edge.

To avoid damaging what's in the box:

• Extend the blade only one or two segments
• Cut along the tape seam without pressing deep
• Slide the blade back into the handle after use
