The best dagger wielding class

There seem to be quite a number of effective dagger-based builds out and about these days. Having just watched "The Expendables", I'm inspired once again to create a dagger-dude. Throwing, slashing, slicin'n'dicin', pinning people to walls, lots of minion killing goodness so you can describe all those neck and head shot one-shot kills, etc. Oh, and combos, gotta have good combos.

So, yeah, just wanted to hear some opinions on what good dagger builds there are out there; what are your favourites and why?
