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. Its small 1.5mm width is suitable for eyeglass screws and other similar small screws.
While this tool is added standard on most knives with the 'Plus' style scales, the Mini-Screwdriver can be purchased separately, to add to any knife with a corkscrew, or simply to replace a lost tool.

• Weight: 0.67g

Variations 

While usually grey, the mini screwdriver included with the 2018 White Christmas Sportsman has a white body.

In 2021, Victorinox introduced a set of four new mini screwdrivers with distinct colors: grey (flat head), green (Phillips #000), blue (Torx 4) and red (SIM card removal tool). These four tools feature the Victorinox logo stamped in the body.
