Is the use of the term Swiss Army Knife trademarked?

Yes, the term "Swiss Army Knife" is a trademark owned by Victorinox, the Swiss company known for producing multi-tools and knives.

As a result, while it is a trademarked name, its usage has broadened in everyday language to refer to similar multifunctional items.
