Man, I don't even know. I'm a martial artist, so I have tons of wooden weapons, a pair of sai, a ninja sword set (two swords in a single leather sheath), some junk swords, a rapier, a bamboo cane, wooden Tai Chi Sword, wooden Kung Fu Sword, several wooden Daito-length Bokken, a thin bamboo stalk I picked up somewhere, a BB gun, several knives, a few throwers, a manriki chain, a couple pairs of nunchucks (I use them quite well, thank you)... I dunno, I'm probably leaving some stuff out.
I'm not a weapons collector. I use everything that I own, with the exceptions of the weapons I own that I'm not yet skilled enough to use (that manriki chain'll kill ya if you swing it wrong-the thing is solid steel).
I want to pick up a fully functional, full tang Katana set, but sadly have no money to do this right now.
Even though I don't tend to like decorative weapons, it's interesting some of the things people come up with. I've seen swords modeled after the ones used by video game characters (and not just popular games- Hotsuma from the PS2 Shinobi has his own sword!), manga (Alita's giant butterfly knife is available online) and anime (those stupid Bleach swords are everywhere.)
