WASP Injector Knife

If stabbing your prey simply isn't enough for you, check out the WASP Injector Knife ($380). Designed for taking out large land and sea predators, this hardcore weapon features a 5.25-inch blade and can hold up to a 24g gas canister, which is used to inject a freezing cold, basketball-sized ball of compressed gas into whatever you've punctured, dropping even the largest of monsters simply and effectively.
