New kind of Knife.

Discussion in 'Cop Talk' started by Trigger Finger, Nov 11, 2011.

  1. I got this from a fellow officer. This thing could blow you up like the Pop-n-Fresh Doughboy. Staying aware of what's out there is half the battle!!
    Stay Safe.

    Officer Safety Item

    Officers should be aware of this knife.

    You might survive a stab wound with an ordinary knife, but this one would be fatal. It delivers CO2 into the body at 800 PSI.
    It freezes all the organs the gas reaches and causes massive damage.
    The knife is available for $499.99 on the internet.

    "This weapon injects a freezing cold ball of compressed gas, approximately the size of a basketball, at 800psi nearly instantly. The effects of this injection will drop many of the world's largest land predators.

    The effects of the compressed gas not only cause over-inflation during ascent when used underwater, but also freezes all tissues and organs surrounding the point of injection on land or at sea.
    When used underwater, the injected gas carries the predator to the surface BEFORE blood is released into the water. Thus giving the diver added protection by diverting other potential predators to the surface."

    An interesting weapon, but its potential lies as a weapon for an assassination style of killing or an anti shark weapon for divers.

    The OSA has a bit of hyperbole in stating that the expanding C02 is going to freeze all organs it comes in contact with. The gas temperature is at its lowest point upon initial release. The properly sharpened blade is going to cause more damage than the gas will.

    The gas is not going to prevent blood from being released, underwater or not. It cannot cauterize the incision. The video itself shows a ton of splashback when triggered. The human body is not a sealed bag that will expand when filled with a significant volume of gas - ala Kanaga in the James Bond movie 'Live and Let Die'.
  4. You are correct, blueiron. But I think that being stabbed is bad enough, then injecting air rapidly into the wound would cause double or triple the amount of damage. I think that the rapidly injected air could also cause allot of Hydro Static shock.

    Just food for thought!!!

    Doesn't really change my existing policy of shooting all *******s coming at me with knives.

    Interesting find though.

    that knife has been on the market for years. still very cool though. first saw it about 6 years ago i think. a few years ago there was a puffed up group in europe trying to make a fuss about street gangs potentially using them. would be very bad for anything that got stabbed by one. but $500 is a lot to spend in a knife for the average thug i think.

    The knives are not new. They are very expensive.

  8. Not new, but relatively unknown outside of the diving community.
  9. Back in the day, just after the earth cooled, when I was on active-duty, we had Farallon shark darts that looked more like a big hypodermic needle and a CO2 cartridge w/a handle (or on a stick, like a bangstick), than a knife like this one. Depending where it was poked, it would displace internal organs and immediately changed the buoyancy equation.

    While you always have to head's up for anyone w/a blade, I agree, $500 is probably more than the average knucklehead is going to spring for a single weapon. On the street, he could probably pick up 2 or 3 stolen guns for that, and they're much less personal...

    Nasty weapon for sure. Another reason to practice the 21 foot rule when encountering anyone with a knife.

    Yes, but we are being trained back to 25 feet, and it will continue to increase and it should.

    This is certainly interesting but it really doesn't worry me any more than any other knife weilding attacker. Thanks, though, for the heads up.

    I saw the big LEO Alert they sent around. As others have pointed out this has been around for years and it really is not that much of a big deal. ANY edged weapon is scary and really fast. It is a contact weapon and not nearly as scary as all the cellphone guns, cane swords, handlebar shotguns etc out there. Hell a bamboo/wood AIDS infected dart shot through a plastic straw is scarier.. and they can readily make that in the joint.
