I like katanas but I find them a little overappreciated. Lots of people like them, but, after all, there are so many great weapons out there, I like them all!
And I like other japanese swords better anyway. A nice tachi and miniature tantos are nifty, but my favorite is the no-dachi, or "Man's sword."
Actually, it was designed both to fight and to be used to cut down thick brush when travelling through forests!
Well, all the "old fashioned" weapons. I'm not to keen on heavy arms, wide area bombs, and biological weapons. They just take the grace out of it, I think.
