SOG EZ1-CP Cash Card Knife
No need to carry a mini blade on your keychain or inside your wallet. The SOG EZ1-CP Cash Card Knife doubles as a money clip instead, with its skeletonized body adding minimal bulk to your carry despite its 2.75-inch 8Cr13MoV steel clip point blade. A solid liner lock mechanism keeps the blade securely open and a shaped handle offers both a comfortable and secure grip.
