Hand instrument

In a hand instrument:

• an elongated handle having a pair of opposed ends,
• there being an elongated cavity in said handle disposed longitudinally thereof and extending inwardly from one of said ends;
• an elongated connector conforming in shape to the cavity,
• said connector being encased within and completely filling said cavity,
• said handle tightly engaging the entire outer surface of the connector therearound to rigidly attach the connector to the handle,
• said connector having an elongated, tubular stem,
• said stem being provided with an innermost end having a solid, essentially spherical boss integral with the stem for holding the connector against inward movement relative to the handle toward the opposite end of the latter,
• said boss having a plurality of outwardly facing, circular, flat surfaces, spaced equally therearound for holding the handle and the connector against relative rotation;
• and
• an elongated, solid shank within the connector and extending outwardly therefrom beyond said one end of the handle,
• said connector tightly engaging the entire outer surface of that portion of the shank disposed in the connector to rigidly attach the shank to the connector,
• said shank having an innermost end extending into the boss for holding the shank against inward movement relative to the connector toward said opposite end of the handle,
• said shank having a pair of elongated, diametrically opposed, radial ribs within the connector adjacent the boss and extending longitudinally of the shank for holding the shank and the connector against relative rotation,
• the handle, the connector and the shank being coaxial.
