CardSharp: the credit card that transforms into a knife

On this year’s “must-have” list for the gadget-lover close to your heart we’ve been intrigued by design house Iain Sinclair’s wallet collection. While our inner-geeks love the wallet-sized HD and 3D cameras, the CardSharp utility knife is equally exquisite. Designed to be stored in your wallet, the knife is the dimensions of a credit card, but with three little folds it transforms into the utility knife you see before you.

The built-in protective sheath protects you from injury and the stainless steel surgical blade from blunting , plus its composition makes it slimmer and lighter than standard knives. Weighing in at just 13 grams and measuring just 120 x 120 x 5mm.

It’s set to ship Q1 2011 for $25 US in your choice of natural stainless steel or black Teflon coated blad. You can reserve it now for half that price and come Christmas morning you can give the gift of a picture of a credit card-sized utility knife! After all, it’s the thought that counts, right?

  1. I bought this. It finally showed up after months of waiting for it to finally be made, and when I finally got it, I found the handle was made of plastic. I still liked it, the blade was sharp and everything. Then I tried to cut stiff cardboard, and the blade broke off the cheap plastic handle. What a waste of money. DO NOT BUY!

  2. I think that this is a very unique idea. It sounds very cool but I wonder about the safety of it. It looks like a cool thing that a lot of people will want to try.

  3. I’m seriously thinking about getting one!

    btw, i tried to ‘thumbs up’ the comment above and nothing happened

  4. I wonder how this would fly (terrible pun intended) with airport security…
