Patent ID: 7401409

Claim:
A device for making opening in a food comprising an elongated shank having a longitudinal axis circular in cross section with a circular peripheral surface and being cutout along a predefined chord to define an elongated flat, a point formed on one end of the shank, a pusher element attached to the other end of the shank, and a ring having an opening circular in cross section and defining a mating flat to form a close fit with the elongated shank, said ring being longitudinally, axially and slidably mounted on the shank with the mating flat of the ring in contact with the elongated flat of the shank whereby said ring can be slid longitudinally and axially relative to the shank, and said ring can be rotated normal to the longitudinal axis of said shank so that the mating flat of the ring is rotated into contact with a portion of the shank that has a circular peripheral surface and create a press fit between the ring and shank to act as a stop to lock the ring in place on the shank.
