Abstract: A self-defense apparatus is provided. The apparatus includes a sleeve sized to fit over an arm of a user, with a forearm portion, and an elbow portion. A housing is secured to the forearm portion. An opening is formed that leads into the housing. The opening is disposed near the elbow portion. A spike is disposed within the housing. The spike includes a first end having a point and a second end having a stop. The stop prevents the spike from fully exiting the housing. The present invention further includes a spring biasing the spike to be substantially outside of the housing through the opening. The apparatus includes a deployed position including the spike substantially outside of the housing, and a retracted position including the spike substantially within the housing.
