The Bit-Driver was introduced into the Swiss Army Knife lineup in 1999.
Its main use is as a 4mm hex bit driver that accepts a variety of double-ended changeable bits. It is also designed for use as a 5mm hex-nut-driver, these nuts are used to secure D-Type electronic connectors often used for serial-ports or older monitor connectors. These connectors however are falling out of use.
The driver is designed for use in the fully open position, as well as in the 90º, or 'half-stop' position, where it forms a right-angle with the knife handle.
The Bit-Driver is paired with a Bit-Carrier in the same knife layer. This is a plastic carrier that can hold three bits, one bit can be stored in the actual driver when the driver is closed.
