Safety
knives

Ten knives in three families. They all cut cardboard, tape, film and strapping — what sets them apart is how the blade gets out of the way once the cut is done.

SAFEAutomatic blade retraction

Push the slider and the blade comes out. Release it — or simply lift the knife off the material — and a spring pulls the blade back into the housing. The blade is exposed only while a hand is working the tool.

EXTRA SAFEFully automatic blade retraction

Squeeze the trigger handle to extend the blade, release it and it snaps back on its own — no thumb slider to hold down. Made for shifts where someone cuts all day and the hand should not stay under tension.

ULTRA SAFEConcealed blade

The blade never leaves the housing. It sits behind a narrow opening — 4 to 6,5 mm on the models below — so there is nothing to extend and nothing to retract. You hook the knife into the material and pull.
