Abstract: Oyster splitting devices split open oysters and clams. A bar clamp has a drawbar slidably inserted through a grip. The drawbar has a stop on one end and a jaw on its other end. The grip has a jaw trigger and a bar release trigger pivotably attached to it. A spike is attached to the grip with the spike's pointed end facing the jaw. An oyster's open end is placed against the jaw. When the jaw trigger is pulled by the user, the jaw urges the hinged end of the oyster against the spike, splitting its shells apart. The drawbar's opposing end opposite the jaw may be tempered and tapered and used to pry oysters from rocks and/or remove meat from split oysters. A safety cover connected to the grip by a lanyard removably covers the opposing end of the drawbar opposite the jaw when it is not in use.
