US Patent 7686472 Self-defense flashlight with protectable sharp edges

A self-defense flashlight includes sharp edges positioned around the head end. A sharp edge protector can be positioned so as to surround and protect the sharp edges, when the flashlight is not being used for self-defense purposes. When needed, the sharp edge protector can be moved so as to expose the sharp edges, allowing the flashlight to be used as a weapon. The protectable sharp edges can also be positioned around the tail end of the self-defense flashlight.
