Folding Credit Card Knife for your Wallet

The CardSharp is an ultra thin knife that conveniently stores in a credit card slot in your wallet. It has a stainless steel surgical blade and a polypropylene handle that only requires three quick folds to transform it from rectangular credit card shape to a super sharp knife. The CardSharp is $25 from Iain Sinclair.

    Nifty, but I think I’ll stick with my Leatherman. FYI your link is broken (missing the h in http).

      @deslock Link fixed. Thanks 🙂

    Another reason for the TSA to frisk you and take away your wallet, I see. 😉

    Ditto for sticking with the Leatherman multitool, but at least this card has a usable(?) handle.

    My Swiss Card has been doing that for years (20?). I assume that you still cannot take it on planes or through security checkpoints.

    Can you unfold it and put it back in your wallet after using it? Their site doesn’t say.

      @Norm Yes, it folds back into the credit card shape. Their site has a video that shows it in action.

    Thanks Julie! These were not available for quite some time, and so now I ordered a few for gifts. I hope they don’t really take 28 days to ship. Your posts are the best!
