Victorinox

The mini-screwdriver was introduced in 1983.
It is quite an ingenious tool, due to the way it is designed to be twisted into the corkscrew, enabling it to be added to any Swiss Army Knife with that tool. The screwdriver's small, 1.5mm width is suitable for eyeglass screws and other similar small screws.
This tool is standard on most models with the 'Plus' style scales. It can also be purchased separately, to add to any model with a corkscrew, or simply to replace a lost tool.
It can also be fitted into some, not all, of the Wenger corkscrews.
