CRKT Big Boy Driver, Black Aluminum Bit Driver Tool

The CRKT Big Boy Driver (brand part no. 9915) is a 3.76-inch bit driver tool from Columbia River Knife & Tool built to handle everything from stripped screws to the tiny fasteners on your favorite folder. A smooth ball-bearing spinner speeds up repetitive turns, while a magnetized tip holds bits securely no matter their size. An included adapter steps down from quarter-inch to four-millimeter bits, so one small tool covers both bigger takedown jobs and precision work on delicate gear.
