Our CC-L is a titanium credit card knife, with a razor sharp carbidized edge. Unlike some other credit card tools, the CC-L is built for a singular purpose - to give you a razor sharp edge that you can always have with you. Constructed from .025" thick 6Al-4V titanium, the CC-L is the exact same size and shape as a normal credit card knife, and is thin enough to flex slightly, so you won't even know you're sitting on it. Deeply impregnated carbides at a Rockwell Hardness of 72 provide a long lasting, razor sharp cutting edge. The perfect back up blade for any situation.
