You might have thought that Victorinox couldn't add anything more to their Swiss Army knives, but some newer
knives now contain a patented, compact mini-screwdriver, which coils up into the corkscrew when not in use.
Uses: Because the mini-screwdriver is detachable, it's
much easier to use (and also much easier to lose). Fortunately, replacement drivers are not too expensive.
In fact, you can add the compact screwdriver to any Swiss Army knife from Victorinox or
Wenger that includes a corkscrew, even if it didn't start
out with the mini screwdriver.
