Matching numbers on scabbard and knife

The St. 57 had a very long service life, remaining in production from 1958–1983.

The "W + F" mark indicates assembly by Waffenfabrik Bern, while "Victoria Schwyz" identifies the blade supplier as the firm, Victorinox, located in Schwyz Canton.

To avoid conflict, the Swiss government gave half of the military knife blade production quota to Wenger and half to Victorinox.

 Victorinox acquired Wenger in 2005, however, continues marketing products under both trademarks.

S.I.G. produced an export model knife to go with export versions of the Stgw. 57.
