Diamaze diamond-tipped razor blades can literally split hairs (video)
At last, a sign that we're advancing from our caveman heritage into a brave new world. Gone are the days of rough-hewn blades, the world of modernity does its cutting with "plasma-sharpened" implements polished off with a layer of synthetic, industrial-grade diamonds. Okay, we're not quite there yet, but we're en route, thanks to a small German outfit named GFD, which has recently debuted a diamond-tipped, tungsten carbide razor blade that promises to retain its sharpness 1,000 times as long as regular steel and to be precise enough to slice a human hair in half. Hell, that latter bit isn't even a promise, it's a fact, which you can verify in the video after the break. GFD is looking for a manufacturing partner to bring this ingenious prototype to market, and given its years of experience applying the technology to industrial uses, we reckon it has enough of a pedigree to stand a decent chance of success.
