The Victorinox and Wenger 1993 Soldier Swiss Army knives are a 93mm / 3 1/2" ribbed alox knife, with a 1993 date on the blade tang. This is the final year with some knives that include a cutting notch in the bottle opener, similar to the 1993 Soldier. The hollow rivet was also discontinued for Victorinox knives, and a few 1993 knives have entirely solid rivets. Both these changes were completed in the 1994 Soldier.
