The Victorinox and Wenger 1992 Soldier Swiss Army knives are a 93mm / 3 1/2" ribbed alox knife, with a 1992 date on the blade tang. This model was standard issue for the Swiss army during 1992. All the knives produced in 92 have a hollow rivet (sometimes with bale). Some knives with a 92 stamp have the same cutting notch in the bottle opener as on the 1991 Soldier, but some do not. The notch is also found on just some of the 1993 Soldier knives.
