Developed by a martial artist and defense expert with over 35 years of experience and two decades of teaching, Preston Ducati created the Sharktooth™ Self-Defense Phone Case to make self-defense accessible for everyone.
“Our phones are always in our hands. So why not make them tools for protection too? That’s how Sharktooth™ was born, from a simple belief that everyone deserves to feel safe wherever they go.”

How to Use
Master how to integrate the Sharktooth™ phone case into your everyday self-defense strategy.
BORN FROM EXPERIENCE. BUILT FOR EVERYDAY SAFETY.
A DOUBLE-LAYER OF PROTECTION
The Sharktooth™ isn’t just built to protect your phone - it’s built to protect you. Its inner layer is a precision-fit, polycarbonate shell that shields your phone from drops, impact, and daily wear. Its outer layer is a shock-absorbing, anti-slip silicone grip reinforced with tactical strike edges, designed to help you react fast and create space in an emergency.
Two layers. One purpose: everyday protection,
already in your hand.
WHEN SECONDS MATTER.
Everyday life feels different now. We walk faster to our cars. We check over our shoulders. We text someone when we get home. The Sharktooth™ was built for the moments we all think about but never talk about.
Join the Hammer Defense Movement
Hammer Defense is more than a product, it’s a mindset. A movement built around awareness, preparedness, and confidence. We believe safety should be simple, accessible, and powerful. When you carry Hammer Defense, you don’t carry fear, you carry control, confidence, and readiness.
