A few Swiss Army knives include a locking, end-mounted Phillips head screwdriver as one of the tools on the main side of the knife. It is a bit more accessible than the rear-mounted driver. On the 91mm knives this tool is in the same slot as the magnifier or LED flashlight, while on 111mm knives it is opposite the scissors.
Uses: On the 91mm standard-size knives, the Phillips
screwdriver locks into two different positions, so you can use it at the end of the knife
(similar to a regular screwdriver), or at right angles (similar to an offset screwdriver).
On the 111mm knives, the end-mount Phillips only locks in the fully open position.
If you have a screw that is very difficult to turn, you can grip this screwdriver blade with an
adjustable wrench or pliers to get more torque-- something that is not possible with a round blade.
