|These knives are ready to rip and run raw. All in one knife: Survival and Combat- can you believe it? The newest additions to the Z-Slayer family are none other than these 13 inch behemoths. They come equipped with any extra modifications one may need in the wild or in the warzone. Yes, that is real stainless steel used to craft the material for the window breaker (or if you like- skull crusher). There is an awesome pattern of deadly skulls that cover the entire dagger only to scare the most horrifying of the undead. There is an easy-to-grip handle with ridges in it for almost any hand size. The blades are razor sharp and made to cut the worse of the most evil in undead flesh.
