On the picture today there is some information about the corkscrew. This is most likely a late 1990s knife. I have discussed some before on the variations with the corkscrew. Between
every evolution change done by Victorinox you will find small variations in the design or shape. This is on an 84mm advertising knife. There must be at least 10 different ones outside the regular evolution made, if not more. This can be a simple thing as shown
on the picture with the front section of the corkscrew having a larger opening compared to the end of the looped shape. There are different reasons for all these variations.
The tang stamps on the main blade are interesting for different reasons. As you know Victorinox use and used many independent markings on a number of categories. Some are for more than one category. It
is the same with the stamps as a number of other Victorinox functions with variations between each evolution marking or stamp. It may look the same at first eye. With a magnifier you will see that it is impossible for them to be made by the same module and
may contain hard to see design changes.
Back to the corkscrew the modifications can be for a number of reasons and they are best to notice with the mini screwdriver.
The main evolution on the Officiers knives are a bit different compared to the 84mm category. Advertising and economy made knives are also different. I will not let go of the angle differences just yet because there
are similar designs with an opening that is a bit bigger. It is not so that hard use forced it in this fashion. The one on the picture is just a bit too much different so it is a variation in itself to me. It is just one of the types that you may see or find
with Victorinox SAKs. It is absolutely not a problem of any kind.
