The CarbonMax snap-off knife can be quickly and easily loaded from the front, with no loose parts. An integrated snap-off mechanism breaks off and collects old blades, so you don't have to worry about loose old blades lying around. The back of the knife is made of reinforced metal for greater resistance to bumps and drops. Includes 1 CarbonMax 25 mm snap-off blade, which lasts 24 times longer than standard blades.
