The corkscrew is amongst the most common, distinctive and iconic features of a Swiss Army knife.
It was one of the two new tools introduced, in 1897, with Karl Elsener's second pocket knife, the legendary Officer's Knife. This model, with its corkscrew, has been credited with saving the fledgling company, and of course, was the start of what everyone now knows as the Swiss Army Knife.
Since that time many bottles of wine have been uncorked, and inventive uses for the tool have been discovered.
A later, and ingenious innovation, was to use the corkscrew tool to store the mini-screwdriver.
Whilst many users appreciate the corkscrew, as corks become less common in wine bottles, there is a large group who do not, especially non-wine-drinkers. These users prefer the back-spring Phillips driver, and the 'corkscrew vs Phillips' discussion is one of the most hotly debated topics amongst Swiss Army Knife users.
The groove in the corkscrew was dropped in 1991 (date in question), although information from Victorinox (dated 2010.02.08) indicates that the 91mm grooved corkscrew was in production until 1994. It has been suggested that this change was a cost cutting measure, as the groove is more decorative than functional. Early versions of the corkscrew have a significantly tighter spiral of smaller diameter that allows a full extra twist in roughly the same length.
The ubiquitous corkscrew is not made in Switzerland!
According to a Victorinox customer service representative in correspondence (2012.09), the corkscrew has been purchased from a French supplier (understood to be from the knife capital of France, Thiers), as a semi-finished part for decades.
Although not everybody drinks wine, Swiss Army Knife users have found a number of additional uses for the corkscrew tool.
Some of these include the following:
- Extracting a fuel filter when repairing an engine
- Extracting the stub of a spent candle from a candle holder
- Extracting plug holders from IKEA furniture!
- Affixing the knife to an overhead beam to hold a mosquito net
- Loosening knots - This is also included as a tip in Victorinox documentation
- Removing cotton wads from pill bottles
The upper image shows the current four-turn non-grooved, and earlier grooved, corkscrews. The groove on this 91mm corkscrew is much less pronounced than that on the 84mm five-turn narrow corkscrew. Early 91mm corkscrews also had the deep groove, the change to the shallow groove and the thicker four turns was likely intended to increase the strength of the tool.
The lower image shows the 84mm narrow corkscrew with a very deep groove.
The corkscrew is equally common on Wenger models.
Note: It is a little tight, but the Victorinox mini-screwdriver can be inserted into, at least some of, the recent Wenger corkscrews.
This corkscrew was also manufactured in a five, and later, a four turn design
