I am pretty sure I got this one at the Airforce Rod and Gun club in Ktown in the early 2000s. It came with a nice pouch or shelve to keep wear to minimum. It’s an 84mm knife and its good for opening boxes or post. It does not feel much like a knife for camping its more a gentleman’s pocket knife. I carry it in rotation to work of small thin knives.
“The Excelsior is a fairly uncommon Victorinox knife (although see History below ).
It is very similar to the common Pocket Pal, but includes a keyring.
There is also a model with Silver Checkered Alox Scales and no keyring.” (From the SAKWikki)
To me the scale stamp is very different than others. The tang stamp only has rostfrie on one side no other markings. So the date is hard to pin point.
