A few knives from Wenger include a driver bit, with a set of bits of various types (phillips head,
slot head, torx, ponzi and hex head). These knives include one or more hex drivers, and an interior tray that holds the detachable bits for it.
Uses: To use the bit driver, swing it
out and lock it in the right-angle or fully open position. You can swap in six additional bits from the
bit tray.
