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.

  2. 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.

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

  4. 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!
