What exactly would you use it for though, other than waving around at burglars? I can't see a martial arts (Aido, Aijutsu, Aikido or Jujitsu) class take it seriously as a wakizashi, a sword doesn't strike me as a hugely usefull woodcraft tool, even INFI...
It would make one hell of a 'conversation piece', but at $600 boy would it have to!!
