New Knife Proof T-shirt Provides Lightweight Protection
So-called "slasher" flicks may never be the same, thanks to an innovative Japanese company's new "knife proof" T-shirts. The owner of Nihon Uni, a uniform maker based in Osaka, Japan, was inspired to create a super-strong yet practical shirt by watching news reports of knife attacks against children and convenience store clerks.
Gun ownership (and gun crime) is extremely rare in Japan so bullet-stopping clothing used by the world's armies is unnecessary. Instead, knives are attackers' usual weapons of choice and Nihon Uni acted on that premise when designing the new anti-knife T-shirts.
Nihon Uni first looked at the tough aramid fiber (often referred to by DuPont's brand name, "Kevlar") used in military body armor, then reduced the thickness and density of the ultrahigh molecular weight polyethylene fiber so that it could be flexible enough to serve as everyday clothing. The resulting T-shirts are about three times as strong as those made from cotton fibers, yet are still light enough to be comfortable and machine washable.
Now there are some downsides to the new protective T-shirts, one of them being the very un-T-shirt-like price... 19,000 to 52,000 yen (approx. $195 to $535) for the short-sleeve version and from 22,000-59,000 yen (approx. $225 to $610) for the long-sleeved design.
Somehow I don't think 7-11 is about to pony up that kind of dough. Nihon Uni also says that while the new T-shirts are slash-resistant, the fabric cannot withstand a direct thrust from the point of a knife. Umm, guys... you might want to keep that little infobit under your hats - robbers can read too. (via Daily Yomiuri Online, image via TechShout)
