"This is a great option for people who want to have a force multiplier tool without having to carry anything extra. Almost everyone has their phone with them all the time these days, so having a hardened case that can protect both the phone and the user is a great idea. No special training is required, just hold your phone tight and start striking the assailant with the corners. It couldn't be any easier to use."

About Self-Defense Training
Do I need any special training to use the Sharktooth case?
No – if you can grip the case and make a throwing motion, like throwing a rock, football, baseball, etc. – then you can use the case to protect yourself.
Is the case heavy?
No – the case is only slightly heavier than your standard phone case.
How is it possible the case can puncture watermelon and break boards, bricks, wood, glass and more?
The Sharktooth case has a proprietary design and materials with an extremely high strength-to-weight ratio, making it highly impact resistant, dispersing force while protecting your phone AND transferring that force BACK into the target.
Carrying a gun is a far better way to protect yourself.
Carrying a firearm is one layer of self defense – and a powerful one; unfortunately, carrying a gun comes with it’s own set of challenges. They can be expensive. They require extensive and ongoing training. They can potentially be a massive liability if you have to use it. Laws are different in every state, so you can’t travel with them. They are heavy and not always convenient to carry. You have to take extra safety precautions in you have children in your house. You can’t take them everywhere with you, like churches, schools, federal parks and more. The Sharktooth phone case is simple, safe and legal. You’ve almost always got your phone with you – so you’ll almost always be armed and not even look like it.
