Abstract: The invention is a curette that includes a tip and shaft that detachably join together to form a working tool member. The shaft has a threaded receiving end that is sized to receive a mating end of the tip. The mating, or proximal, end of the tip includes a corresponding threaded section and a smaller-diameter outwardly extending elongated section that is flattened on one or more sides.

The user then screws the tip and shaft together, to interlock, or self-lock, the threads. When the epoxy thereafter hardens, the tip is firmly held against rotation relative to the shaft both by the epoxied and interlocked threads and the flattened-sided section that, because of its shape, resists rotation within the hardened epoxy.
