Abstract: A self-defense device generally comprises a wearable piece of jewelry, such as a ring, that comprises an integrated blade element. The ring comprises an inner diameter sized to accommodate a user's finger or the ring may receive size inserts to effectively reduce the ring's inner diameter so as to accommodate a size of the user's finger. The blade may be serrated, barbed, hooked, and the like to provide for a more effective device. The blade may comprise various supports to add rigidity; may be contoured to accommodate the form of the user's finger; and may comprise a sheath to secure the blade during non-use. The self-defense device may also comprise multiple rings secured together to provide for multiple blades.
