ABSTRACT:
A screwdriver or the like has a shank adapted to hold any one of a number of double ended bits together with a handle for the shank having storage slots for those bits not being held in place by the shank. A split ring, rotatable on the stem of the handle, holds the stored bits against displacement until the ring is rotated to place the space between the ends of the ring into alignment with a selected slot.
