i heard somethin similar. apparently there was a freak accident in the scrap yard labs facility and some uranium fell into the austenite and contaminated it, creating a nuclear austeninte cementite shock steel that created perfect bands in the grain that could be martenized without creating stress in the blade thus antiquating the tempering process! it doesn't even make contact with the media it cuts, it radiates and separates the matter. never needs to be sharpened and comes in an antimatter sheath. it would be guaranteed beyond doomsday if anyone was still around to use it, or replace it.
