A simulation by Zack D. Films demonstrates how the ‘world’s deadliest knife’ can be used to survive a shark attack. Watch the video to see how this unique weapon works and its controversial effects.
In a mind-blowing new simulation, YouTuber Zack D. Films has revealed how the “world’s deadliest knife” works in the event of a shark attack. The simulation showcases how a specially designed knife could potentially save your life by causing the shark to explode from the inside.
Zack D. Films is known for documenting fascinating, often terrifying, simulations, from explaining how a tooth can kill you to how you could survive being buried alive. But his latest viral video explores a new level of danger—how the wasp injection CO2 knife could be used to fend off a shark in the wild.
The simulation explains that the knife works by stabbing the shark and then pressing a button located on the handle. This action triggers a CO2 canister hidden inside the blade. As the canister bursts, compressed gas is shot through a tube in the knife’s blade, which then exits the tip. The freezing gas rapidly expands and is injected into the shark’s wound, causing internal destruction of tissues and organs. The shockwave generated by this violent expansion is said to be enough to destroy the shark from within, theoretically ensuring the user’s survival.
This powerful tool, known as the WASP (Weaponized Anti-Shark Projectile) injection CO2 knife, was initially developed by divers to protect themselves against sharks in the open waters. Blade City explains that this weapon injects a freezing cold ball of compressed gas, roughly the size of a basketball, at a pressure of 800psi. When used underwater, the shockwave can cause dangerous over-inflation during ascent, while on land or in water, it freezes and destroys tissues around the point of injection.
While the simulation shows just how effective this weapon could be, there is no footage of the knife being tested on an actual shark. Instead, the knife has been tested on ballistic gel, plastic bottles, and watermelons to showcase its mechanics. Despite the lack of actual shark footage, the concept has sparked mixed reactions among viewers.

The knife, which retails for $500 for the standard model and $600 for the larger WASP Bowie model, has divided opinions. Some viewers feel that the idea of exploding a shark is cruel, arguing that sharks are generally not violent unless provoked. One commenter stated, “The worst part is about exploding them, sharks are actually pretty harmless if you don’t alert them.” Another person added, “That’s so mean. Sharks aren’t even normally violent unless threatened or something like that.”
While the knife’s effectiveness in self-defense is debated, it certainly raises questions about the ethics of using such extreme measures against wild animals. Whether this knife would ever be used in a real shark encounter remains uncertain, but the simulation continues to captivate those interested in unique survival tools and the mechanics of extreme defense.
