Abstract
A 12-in-1 precision hand tool has five double-ended specifically sized precision tool bits stored in separate handle compartments adjacent the handle proximate end and one double-ended tool bit operably disposed at the distal end of a selectively retractably extendible shank for impeded access precision drive use. A handle cap is removably attached to the handle and has a rare earth permanent metal magnet disposed therein and operably disposed with respect to an axial opening in the cap to slidably receive and magnetically hold one selected double-headed tool bit. The removed handle cap provides a mini 12-in-1 precision drive tool. The handle has alternate flat and arcuate surfaces of about equal surface area and distally disposed contiguous tapered flat surfaces for ergonomic precision tool use.
