Do you mean this: http://en.wikipedia.org/wiki/Vorpal_sword ?
I've read that wikipedia article but I haven't found anything about "infinite thinness" or stuffs like that. Well, if I'm wrong, could you provide some kind of link or more info?
Ohetsu's (I wanted to write Kotetsu) blade reminds me about nr 6 from this link: http://listverse.com/2013/11/16/10-mysterious-swords-from-legend-and-history/
Yeah, I probably shouldn't have quoted urban dictionary :(
Forget the infinite part
