Just look at the video, it's amazing:

"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"
The video features a single edge laboratory blade, but maybe, if it ever reaches the market, we'll see some DE blades. I'd love to see that
