The GoGuarded self defense ring was developed for a local inventor who was also a runner in order to promote runner safety.  This product is always worn by the runner but looks very non-threatening visually.  Unlike pepper spray or other similar products, this design is always at the ready in case the need arises and can be used to slash or stab the attacker in order to get away to safety.  The simple yet elegant design consists of a glass filled nylon plastic ring and blade with a  TPU rubber sheath and multiple inserts for various ring sizes.
