ABSTRACT:
A ring blade for cutting or for defensive purposes comprises a ring with a top section and a movable crown member mounted in this top section. The ring is adapted for placement on a person's finger. The crown member has an elongate slot formed therein and a blade member is arranged in this slot. First and second pin members are provided to pivot the blade member from a retracted position where the blade is located in the slot to an extended position where the blade is exposed. The blade member is connected to the top section by one of the pin members and it is connected to the crown member by the other pin member. Movement of the crown member towards the top section causes the pin members to pivot the blade member to the extended position. Preferably the top section has a V-shaped cavity and the crown member is also V-shaped so as to fit inside this cavity.
