Blade's throwing knife probably wouldn't make a very good thrower in real life; movie magic made it seem really neat, but the design looked a little unworkable. I seem to recall that it spun around in complete circles reminiscent of Xena's Ultimate Frisbee. Also, if I remember correctly, a copy of the Blade sword can be had from the maker, Tony Swatton, for only a couple of thousand dollars or so. The folks over at www.swordforum.com were talking about it.
