At the risk of sounding like a fiddly-toy-elitist, I have to say that I prefer practice butterfly knives. There's a wide variety of tricks to learn and it takes some hand-eye coordination. Of course, they're also louder, and tend to freak people out until I point out that it's not sharp (and probably a while afterwards too).
