Ever since homo erectus figured out how to use a hand axe, we as a species have endeavored to find better and more efficient means of ventilating our enemies and competitors.
Through the years, down through the generations, various cultures have given us a cornucopia of edged weapons. The katana. The halberd. The khukri. The hand-and-a-half bastard. The gladius. The flamberge.
All of which have been rendered obsolete, due to the advent of pelletized death, i.e. the self-contained firearm cartridge. The bad thing about ammo: when the zeds have overrun the munitions plants, the ammo runs out. Unless your rifle has a bayonet on it to convert it to an ersatz spear, it's going to just be a paperweight. So, it never hurts to have a backup handy.
These days, the zombie craze has inspired a new generation of bladesmiths to offer edged weapons that incorporate modern styling and metallurgy, giving new life to the old ways.
These aren't toys. They may be based in whimsey, but they also seem to be gorgeously tough and reliable tools.
Fallen Oak Forge is a small operation that offers beautiful micarta-gripped blades, and a high degree of customization. You can "like" his stuff on Facebook (click here for the link to his ZdaySurvivor47 page), or buy his stuff from his Etsy shop. The gear-head cudgel (club, for you Philistines), really strikes my fancy.
Zombie Tools is a bunch of PBR-swilling Montanans that make some devastatingly nasty blades. I particularly like the Hellion, Reaper, Deuce, and Vakra. They're also on Facebook.
Are these blades expensive? Hell yes.
I don't own anything from either company, and it would take some major coin to fulfill my wishlist. But I admire their craftsmanship and roll-up-your-sleeves work ethic.
If you're on a budget, I'm sure a GI-surplus machete, Khukri-Style Knife, or a Vietnam Tomahawk will do the job just fine. Good tools from reputable companies don't have to cost an arm and a leg. Just make sure you buy quality, and research the less-expensive stuff thoroughly.
Remember, your life just might depend on it. ;)
