As if Japanese swords weren´t sharp enough, new research in shows that scientists have developed new improved swords that are 6 times,...yep...6 times more resistant than ordinary steel swords. And also withstand subzero temps with ease.

The labrats at The National Institute for Materials Science have found a way to develop crystal structures within the swords in a process that one researcher likened to making a pie.

¨The iron material is turned back on itself in layers and hammered; the process is then repeated more than a dozen times. This appears simple, but through repetition, strong and tenacious steel with fine needle crystals is formed.¨

Whatever you say, just don´t get angry man.
