Wasp Knife - How it Works
The Wasp Knife, which the news media has been reporting on recently, is extremely deadly. This is the way it works:
- in the knife handle, there is a small canister of 24 grams of compressed carbon dioxide (CO2)
- there is a small tube running from the canister opening to the tip of the Wasp Knife blade
- when a small button in the handle is pressed, the knife discharges the compressed (and extremely low-temperature) CO2 through the tube at approx 850 psi
- if something (or someone) is stabbed with the Wasp Knife and the button pressed, a basketball-sized area of their tissues can be instantly frozen (which is very, very deadly)
This might be a useful feature if you're an underwater diver and a great white shark is attacking you - the shark's tissues are snap-frozen, but also the influx of gas can exert upward pressure on the buoyant shark, which will only increase internal pressure as it approaches the surface.
But this sort of weapon can easily get in the wrong hands and be far more deadly than a knife or dagger. The knife is sold for $380 from WASP, usually to hunters, pilots and divers who might run into bears, sharks and other deadly animals.
Understandably, its ready availability has plenty of law enforcement authorities concerned. (See news items about the Wasp Knife at the bottom of this page)
A British friend of mine had this to say:
In the UK, they also worry about Swiss Army Knives, child-grade pepper spray, plastic bb guns and aggressive-looking bananas. :)
This is not much more than a gimmick from a person-person perspective. A human would be unconscious from a severed artery in less than 30 seconds, and dead within minutes. You don't need a $380 turbo-charged, inter-cooled knife for that. If anything, the emphasis on stabbing puts the attacker at greater risk of being disarmed. Knives are far more effective as cutting as opposed to stabbing weapons.
I can see how the Wasp knife might be useful against an attacking wild animal. But it's even better at impressing your mates by blowing up fruit, household objects, bicycle tires...
