I've been fascinated by edged weapons ever since I was but a wee laddie, knee-high to a hairy haggiss. I don't have much of a collection (I've been trying to streamline my material posessions: I don't like being too attached to much stuff, and plus I need money), but I do have a couple axes (all utilitarian), a machete, a respectable collection of pocketknives, a pirate cutlass, and my pride and joy: An ancient (well, alot older than I am, anyways) Bowie knife that I sort of inherited from my grandfather.
When we did Wilderness Survival merit badge, Randall Flagg (that's what we nicknamed the merit badge counciler, because I swear that's who he freakin' is) brought out a whole mess of different knives for us to try out, and I've decided that my favorite sidearm type weapon is a Nepalise kukri. I LOVED that thing.
The weapon I'd take into battle? Why, a braid claymore, of course. Unless I was fighting zombies; then I'd go for a nice, utilitarian machete.
EDIT: Sharpened rebar works, too.
'NUTHER EDIT: Y'know what? Scratch that. If I'm fighting zombies, gimme a Dutch garden spade with a wooden handle and a steel blade. Keep 'em at a safe distance.
