Duragrip 18mm Auto Load Snap-Off Knife

Ideal to have to hand on many jobs, this retractable knife features 18mm snap-off blades that, unlike most utility knives, give 8 sharp edges per blade. Housed within a heavyweight casing with soft grip for comfortable working, the blade extends and retracts smoothly via push button mechanism. The blade snapper is built into the end of the casing for safe, easy snap-off when the previous edge is spent.
