Welcome to Engines of Mayhem. This site is devoted to producing and selling practical, affordable self-defense tools that will function as expected. Too many sellers of products like these are merchants, but not themselves students of self-defense. Engines of Mayhem, by contrast, is staffed by dedicated self-defense practitioners with many years of experience in martial arts, combatives, the use of knives and impact weapons, and the theory and practice of personal protection.
