From Noah Shachtman’s “Chameleon Weapons Defy Detection” (Defense Tech: 27 March 2006):
Last week I talked to Anthony Taylor, managing partner of an outfit which makes weapons which can be hidden in plain sight. You can be looking right at one without realizing what it is.
One type is the exact size and shape of a credit card, except that two of the edges are lethally sharp. It’s made of G10 laminate, an ultra-hard material normally employed for circuit boards. You need a diamond file to get an edge on it.
Taylor suggests that the card could easily be camouflaged as an ID card or one of the many other bits of plastic that clutter up the average wallet. Each weapon is individually handmade so they can be tailored to the userÃ¢â‚¬â„¢s requirements.
Another configuration is a stabbing weapon which is indistinguishable from a pen. This one is made from melamine fiber, and can sit snugly inside a Bic casing. You would only find out it was not the real thing if you tried to write with it. It’s sharpened with a blade edge at the tip which Defense Review describes as Ã¢â‚¬Å“scary sharp.Ã¢â‚¬Â …
