swiss army knife questions

[rainydayarmadillo]

the other day I was at the Flea Market and bought and Sak executive. at first i didn't really look at it but when i did i noticed it still said "rostfrei" on the knife and the scissors had a screw in it. does anybody know when victorinox stopped putting those things on the knife so maybe I can have an idea of when it was made?

Rostfrei (rust-free) is from 1975 to 2005.

Screws were used between 1980 and 1991 in the scissors.
