Iain Sinclair Knife

Iain Sinclair’s Cardsharp2 looks like a credit card, but when an emergency strikes, it folds out to reveal a functional knife, all for just $3.99 shipped – today only. This updated version is not only lighter, but slimmer as well, due to its 420-series surgical stainless steel makeup. This tool may not be as large as its hunting or kitchen counterparts, but it’s sharp enough to easily cut through a seatbelt. You can pick one up for just $3.99 shipped here.

This 007-inspired tool was originally designed as a lightweight surgical knife that anyone could easily transport and safely dispose of, mainly by hospital and medical center employees, without needing expensive and wasteful sharps containers. Its unique surgical blade technology features an extra long 65mm cutting edge that ensures longer lasting sharpness (conventional utility knife blade edge is only 25mm long). A good test is to carefully cut through a tennis ball or two inch foam which is more difficult using a normal carton knife. More information.
