A Last Line of Defense

For Ocean Goers against Sharks



Biting back at pollution, one recycled ocean plastic product at a time.


We started Biteback because we want clean(er) oceans and we'd like to see a market flooded with products made with recycled ocean plastics.

The first novel idea that popped into mind was a spike to help ocean goers feel safer and increase their odds of survival if a shark were to become curious or aggressive.

The 316 stainless steel spike has a handle and sheath made with recycled ocean plastic. It is NOT designed to kill, but offers you better chances at fending off sharks and letting them know you are not an easy meal.

The low profile holster sits comfortably out of the way and keeps your Biteback secure, yet easily accessible in case of emergency.

Protect yourself and help clean up the ocean.

By purchasing this product you are contributing to cleaning up the marine environment of plastics. Not only that but part of the proceeds will be donated to marine conservation efforts worldwide.


• 316 Stainless Steel Spike.

• Durable and easy to grip handle made with recycled ocean plastics. High vis orange colour and it floats.

• Sheath, also made with recycled ocean plastics, also high vis orange and floats. Easily detaches for quick access to spike in case of emergency.

• Low profile, superstretch neoprene carrier. Tool slides into built in pocket and secures safely to the outside of the upper arm(s). Provides quick and easy access to the tool, in case of emergency.

• Rugged and durable lanyard for easy access to tool, in case of emergency.


When we enter the ocean we must consider and respect the shark, because we are in their natural environment. Nonetheless, finding yourself in the company of a hungry or curious shark is not a good feeling, seeing as we have no natural defense.

We do have brains however and research has shown that the eyes, gills and electroreceptors concentrated around a shark's snout (Ampullae of Lorenzini) are their most sensitive parts. Therefore we've designed and developed The Biteback to help fend and fight off these apex predators and increase your odds of survival in an "investigation" or attack.

Who's it for?


...I like that it can be accessed quickly in an emergency. When I was bitten by a Grey Reef shark at Enewetak Atoll, it would have definitely come in handy. I was bitten on my left hand and my partner was bitten on his right arm. Even though he had a bang stick mounted on his backpack, there was no way for me to remove and activate it, since it would have required two hands. I can see how your product would be a lot easier to use, plus would not be nearly as dangerous to use. It's nice to know it won't kill the shark either!

I like the Biteback's design. Its simple.  Next time, I'm biting back!
