Our Story
Feeling safe shouldn't be scary
"Too many of us know that gut feeling of walking to our car in a dark parking lot and hearing a noise behind us."
Kate Davis created Knockout because self-defense products shouldn't look scary or feel bulky. Every ring, spray, and alarm is designed to fit seamlessly into your daily life.
