These finally arrived after a 7 month wait!
There are many pocketknives and multitools designed in a credit card shape, and supposedly meant to be kept in your wallet. But most of these knives are a little bit too bulky to actually fit in the credit card pockets of your wallet.
Not so with the Iain Sinclair CardSharp. The CardSharp utilizes a creative and unique folding method to allow the knife to maintain a much smaller profile. This pocket knife easily fits into the same space as a couple of credit cards. The secret is the almost-one-piece design; the knife lacks the liners and pins that add to the thickness and weight of a normal pocket knife. Additionally, once fully deployed, there are no concerns about the knife closing when you do not want it to.

More information from the manufacturer:
Kept conveniently and safely in a wallet, the lightweight CardSharp® at just 12 grams will always be handy (far lighter than an ordinary pocket knife). With surgical blade technology made from non-rusting stainless steel (heat treated with an ultra tough black oxide finish), this invention is as clean and as sharp as a carton knife and highly suitable for anything from carton opening, cooking, DIY, camping, gardening to pencil sharpening.
Also ready for any emergency situation, CardSharp® is an invaluable life saving utensil for doctors and paramedics.
“Its an instant conversation piece!” said inventor, Iain Sinclair. “My target was to design a knife that was lighter, safer, easier to use and more pocketable than a Swiss army penknife, but what I ended up with is a product that has a greater wow factor than any other utility tool I have ever seen.”
