Abstract: A meat tenderizer device comprising a body having a tubular portion and an enlarged head. A plunger is mounted for reciprocating movement within the tubular portion and has a seal thereon thereby isolating the volume between the seal and the head. The head has circumferentially spaced axially extending projections with tapered points and passages extending from the projections to the area within said tubular portion between the seal and the head. The passages have one end terminating in spaced relation to the points and the other end extending axially and radially inwardly to the interior of the tubular portion of the body.
