Abstract: A personal toothpick comprises a curved handle with a thin wire hollow form at each end, designed to enter the smallest space between teeth to extract impacted food particles in between teeth and gums. The handle is of a modified s-shaped configuration with thin wire forms extending outwardly therefrom at each extremity in a set shape and being mounted to the handle at their ends.

Abstract: A retractable and reusable self-locking fastening device in the form of a commercially available rivet, pin, threaded bolt or stud and the like for insertion into a sized clearance hole in a workpiece includes a shank means having tenon and pilot means which comprises two successive steps of lesser diameter formed on at least one end of the shank means. Mounted on and fixedly connected to the pilot means is a lug means having a generally truncated conical shape with one closed end and the end remote therefrom being opened to define a space in which the tenon means is disposed, and a sized aperture in the closed end to enable the lug means to be fixedly connected to the pilot means. The tapered walls of the lug means have at least four outwardly extending movable sections separated by at least four longitudinal slots defining a truncated cone configuration.
