Credit Card knife

 Credit Card Folding Safety Knife


Three ingenious folding operations metamorphose CardSharp from credit card size to utility knife in a flash of hi-tech origami.

CardSharp includes several clever safety mechanisms including:

• A built in safety sheath that cannot get separated from knife (many serious accidents happen with conventional pocket knives which users forget to close and put their knife away, still open in pocket, camping bag or kitchen drawer etc).
• A subtle protective hilt that appears when the knife is in an open position and prevents the hand from slipping onto the 2.6 inch (66mm) long blade.
• A snap open lock mechanism that enables the knife to be opened using one hand and ensures the knife is safe and secure to use once opened with no blade tremor (conventional carton knives suffer from poor blade tremor). Fold mechanism impervious to water and rusting.

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.

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.
