CardSharp 4 Metal Credit Card Folding Knife

Dec 4, 2019

Category: Gear

Ian Sinclair’s folding credit card knife receives another iteration this year in the CardSharp 4. This time around, Sinclair has ditched the stainless steel blade nestled within the polypropylene body in favor of a natural CNC machine aluminum metal build.

The device still operates exactly the same – a concealable knife that folds up into a credit card. There were some complaints about the older version randomly opening, and to address the issue Sinclair added a two-stage Zytel locking mechanism that should prevent this from happening. The new version is also much lighter, weighing in at a mere 24 grams. Don’t let the small size of this knife fool you either. The 2.5 inch stainless steel blade promises the same cutting power as a surgeon’s scalpel, and it unfolds in just 3 ingenious steps. [Purchase]
