The "ball" which houses the folding screwdrivers is formed from high impact plastic, approximately 1-1/2" in diameter. (37mm)

Background
Introduced in 2000 by LKL Innovations, Ltd. Production discontinued a short while later.
Despite the plastic in its construction, the ScrewBall is surprising well built. It is an altogether satisfying little tool. Perhaps its primary shortcoming is the ball itself, which creates a somewhat uncomfortable lump in one's pocket.
