<p>The screwdriver includes a three piece cylindrical frame housing an internal rotatable gauge. The rotatable gauge in use aligns one of nine different screwdriver nibs or bits. The nibs are extended through a built-in spring system. The three piece cylindrical frame may be extended and contracted by pulling and pushing the frame from either end, thus exposing the gauge. Nine screwdriver nibs may be housed within the frame thereby eliminating the need to handle each nib individually. The screwdriver may be used to replace a set of watchmakers screwdrivers.</p> |
