What is a Wasp Injection Knife?

A few knives are very special and can cause serious injury. These knives can do everything, from cutting up an apple to killing large prey such as a shark. A wasp injection knife is one example of this type of knife.

A group of knife designers tried something new in 2008 and created the Wasp injection knife. It is also known as the “world’s most deadly knife”. This unique design is also used in ballistics knives and uses compressed gas to inflict maximum harm to the target.

The Wasp injection knife can be used to inject high-pressure CO2 gas directly into the wounds of stabbed targets. Inside the knife’s handle is a cartridge that contains the high-pressure gas. After the knife penetrates the skin, the compressed gas is pushed immediately at the push of a button.

The manufacturer claims that the effects of the wasp knives work on both dry and wet land. The injection also freezes organs near the site of injection because it compresses CO2 gas at subzero temperatures.

A wasp CO2 knife’s blade is made from 440C stainless steel. This steel gives the knife a sharp edge and excellent corrosion resistance, so it can be used in harsh environments such as the deep sea.

What does a wasp-injection knife do?

The Wasp CO2 knife’s secret is its replaceable handle. This hole runs from the handle to where the blade ends. The cartridge’s compressed CO2 is released at high speeds via the hollow portion of the blade by pressing the button near the guard.

The knife can inject compressed gas at 800 PSI immediately. Overinflation can cause damage to target organs, such as lungs, if the compressed gas is injected underwater.

Who uses a wasp injection knife?

Divers originally created the CO2 injection knife to defend themselves from marine predators. Any sea creature it was used on suffered severe injuries. When the knives were injected into sharks, the knife caused them to vomit most of their internal organs when they reached the surface.

This knife can be used to kill the deadliest and largest creatures on land or in the ocean with one shot. It is also easy to use, reload, kills silently, and it is very simple to carry. You can also attack the enemy only once so there is no risk of them coming back to attack.

The Wasp injection knife works best for divers, hunters and outdoormen as well as military and tactical defense forces.

The Downsides of the Wasp Injection Knif

This is a close-range weapon.

You must be near your enemy to use the wasp knife. Imagine being close to a bear, lion or other animal that can kill you in one blow.

A spear or a long-range weapon such as a knife is better and more effective for these dangerous animals. It is therefore not practical for outdoor hunters to use a knife against dangerous beasts.

This weapon is useful for divers as a shark may sometimes come within reach. The wasp knife allows divers to defend themselves in such desperate situations. This weapon allows divers to enter the deep seas knowing that they can defeat deadly sharks in one shot.


The wasp knife, a highly specialized product, is expensive. The standard model is priced at around $500, while the larger model costs about $600. Prices may vary depending on where yours is purchased.

Wasp Injection Knife Cartridges

How many CO2 shots can you squeeze from a single cartridge?

A wasp knife cannot inject CO2 more than onceOnce you have taken a shot, remove the handle and insert a new cartridge. If you don’t have multiple knives, the knife cannot be used to attack multiple predators simultaneously. The good news is that it comes with three 12-grain CO2 cartridges.

Which CO2 cartridge should I use for a wasp knife?

The manufacturer specifies that the wasp injection knife includes three 12grain CO2 Cartridges. It can also hold a 24g gas cartridge. You can achieve this by using a Max adapter, which can be purchased separately.
