A hand tool with a detachable working piece includes a handle having a stud extending out from one end of the handle and a working piece detachably attached to the end of the handle. A locking pin extends through the working piece and the stub of the handle to prevent the working piece from inadvertently detaching from the handle. The locking pin has two steel balls movably mounted in the locking pin and partially extending out from the locking pin to prevent the locking pin from inadvertently detaching from the handle and the working piece. The user can change the working pieces rapidly and easily to deal with changing requirements. Furthermore, the hand tool will save money and storage space because only one handle is needed.
