Just gonna point out, while I loves my swords (and axes, and spears, and knives, and cleavers... you get the idea) I would use them sparingly if ever on zombies. All I need is for the blade to bind up in the bone during a frenzied melee and take
just too long to yank loose and get me bitten. So yeah, its primarily blunt objects for me in the case of the zombie apocalypse. My bokuto is an obvious choice, and I do in fact have some experience fighting with a shovel
As a bonus, if (when) I break a shovel smashing open zombie skulls, that's just a bit easier to replace than a sword.
I'm still slightly torn on the firearms subject though, got a tossup between this lovely 12 gauge (I'd actually probably let Clicky have that one for close encounters) and this lovely little carbine my grandpa left me. Don't have a whole lot of surplus ammo in it's size, but lucky us there is a gun and ammo shop right up the road and we live in the middle of nowhere. So, we might could get there before panicky survivors empty it of everything useful
