Not sure if these guys got the memo or not, but the zombie craze was so 2012. Anyways, the folks over at MeleeMods.com are behind these blade attachments. They start at $110 for their Gatchet model and $120 for their Tact-axe model.They are made from 1065 carbon steel and are black anodized. The Tact-Axe fits on any Picatinny rail while their Gatchet fits on most handgun rails. Only 250 of each were made. Oh and they’re not sharpened so you’ll have to sharpen them before you go slaying zombies, or dragons or whatever.
