Victorinox Replacement Mini Screwdriver

The Victorinox Replacement Mini Screwdriver (A.3643) is a spare part rather than a standalone tool: a flat-head mini screwdriver bit that slots into the corkscrew of Swiss Army Knives measuring 84–111 mm closed. Its main job is tightening eyeglass screws and other small fasteners too fine for a knife's regular screwdriver tip. At just 1 g it adds essentially nothing to a kit's overall weight, so this is really a replacement item for owners of a compatible Victorinox model who have lost or worn out the original bit, rather than an accessory you'd add for hiking purposes. It ships in the standard gray finish; Victorinox does not publish further specs such as material or tip hardness for this particular part.
