*I would like to make it clear that I was not paid to talk about this product, but that it is so cool I couldn't help but share what I know.*

If you're a weapon/knife enthusiast like I am then you'll appreciate what WASP has brought to the table. Originally made for divers, WASP's Injector Knife is the blade equivalent of a one-shot-one-kill.

The Injector Knife releases a blast of CO2 at 800 psi from the top of its tip into whatever has the serious misfortune of being at the wrong end of this thing. The reason why this was made for divers is because of the properties of expanding CO2. Not only does the gas rapidly expand and cause trauma to the cavity of the being, but it also freezes the blood preventing the further attraction of predators. The excess gas now in the victim causes it to float up and away from the diver, further reducing the risk of attracting larger sets of teeth. The Injector Knife has since been applied for outdoor and tactical uses. Some national parks or nature preserves don't allow firearms to be carried, so what do you use in an area known for mountain lion or bear attacks? WASP gives us the answer.

As you can see in the cutaway diagram above, the Injector Knife is as gnarly inside as it is out. Housing a 12g CO2 cartridge (or 24g if the adapter is bought) in its removable handle, all it takes is the press of the release button and all your troubles are over as that ball of freezing gas hits the cavity of the victim. Here's what it does to a watermelon, just for frame of reference:

The first reason I wanted to talk about this knife is for its safety value. There are plenty of people who are put into situations like those I described where they have to worry about possibly facing a predator. A handgun is an easy fix, but only if you hit the animal in the head or heart; otherwise, you run the risk of it advancing and attacking. And some people don't like to carry guns or own them in general, but still have the need for a solid backup plan. The WASP Injector Knife allows an ease of mind, since it doesn't need to be precise and it doesn't take any training or practice to use.

The second reason I wanted to talk about this knife is because it is one of the few times I have seen form and function come together beautifully. As you can see from the diagram above and the pictures below, inside and out, it looks wonderful. The engineering is solid, the design is appealing, and the materials are quality; the blade is surgical steel, and the handle can be neoprene (those below) or rubber.

Overall, I think this is one of the coolest things I've seen in a while, and I might even buy it one day too.

Stay safe, my friends.
