I don't know why, but somebody on my server had this for sale in the Bazaar for 50pp. Needless to say I snatched it up in a heartbeat.
The shadowknight I was playing at the time is only level 6, so I won't be seeing the full damage from this thing for quite some time, but the 37 delay is faster than just about every other 2HS in the <100pp price range, so it's still a decent choice.
Makes me want to level up faster so I can get full benefit from it though. :)
