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.”
