I merely wished to point out that there might be awkwardness of a sort that is utterly uncontrolled. And I'd like to leave it at that, as otherwise the thread will end up in a direction away from its original intent and into one that I don't wish to see it go. There's other threads with plenty discussion on that.
Otherwise though, I agree. While holding a weapon, you can't exactly use your hands for other things, which is what most martial arts focus on. Something with kicks could combine with it pretty well though.
