Abstract: The plastic syringe destruction device employs a cylinder and piston compaction unit together with heat to thermally smash plastic syringes into a compacted mass or slug. During compaction, the syringes are heated to temperatures between 100.degree. C. and 200.degree. C. to bring about melting of the syringes as well as sterilization. A removable transparent cover is also provided to permit only individual depositing of syringes into the cylinder when the main cover is in an opened position. A water injector nozzle is also provided as an option to permit compaction in a dry or wet state.

Abstract: The handle is made by casting in a two part mold. The lower mold part includes a vertical split post having two vertical spaced posts with their upper ends in the form of lateral tabs. The upper mold part has a flat wall member cooperating with the lateral tabs.

Abstract: A detachable cutting blade assembly includes an elongated handle having a rear end and a front end on which a cutting blade can be detachably supported and a blade-locking member, in the form of a wall, is secured to the top surface of the front end of the handle. A portion of the wall of the blade-locking member has lateral lips which give the wall a T-shaped cross section and this provides securement for a cutting blade. The lips of the blade-locking member are aligned with a hole in the handle and this permits the entire handle to be made with a two-part mold in a relatively inexpensive molding process.
