Because I need a pocket knife for hiking in the mountains, I wanted to have a pocket knife that meets certain requirements, but stored too much ballast of unnecessary tools. I've found the ultimate multitool 8361 FORESTER, red / black with corkscrew. In this one can namely wonderfully accommodate these Victorinox mini screwdriver - absolutely suitable for eyeglass wearers, "the ever have a screw loose".
The processing of reviewed here screwdriver I call quite sufficient for the small screws of spectacle frames. For a lot more of the screwdriver is but perhaps also not suitable or intended. The fact is that he is actually not to lose because it is firmly seated in the corkscrew. If you lose the whole knife, then that is of course bad luck.
