This General Tools pocket screwdriver is quick and handy to use when precision screwdrivers are out of reach. It features reversible 1/16″ and 1/8″ slotted screwdriver tips, and #0 and #1 Phillips tips. The driver comes with removable end caps to avoid pierced or torn pockets.
You can find these at Amazon for about $4.50, or local home improvement stores for about $3 or so.
I actually prefer Stanley’s version, but they’re hard to find online without hefty shipping fees.
