Basically Ohetsu blade is "vorpal", it means its edge has infinite thinness and therefore can cut through absolutely anything with no resistance at all.
And he hasn't even gone shikai! :O
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/
