hi all,
I've had a Tsunami for several months, and I like the blade and the weight and the handle just feels darned good. the only minus I could personally think of was the lack of an integral guard on such a knife. the blade isn't exactly for utility though it could be it's secondary function. for slashing the tanto shaped tip provides ample area to do such, for stabbing however, that is at your own risk without a guard. the sheath I thought was actually not bad, better than the standard nylon affair. the quality of the leather was impressive to me as well...i haven't done any cutting tests really just cutting up and slashing cardboard. it's definitely a nice knife for the money and i wouldn't be afraid to use it hard in a utility situation.
hope this helps a little
