The Victorinox and Wenger 1982 Soldier Swiss Army knives are a 93mm / 3 1/2" ribbed alox knife, with a 1982 date on the blade tang. This model was standard issue for the Swiss army during 1982, and it is relatively uncommon.
Soldier knives with an 82 date have a hollow rivet, a cutting notch in the bottle opener, and a square box for the Waffenkontrolle inspection stamp. Victorinox knives have a polished blade, while Wengers are matte without visible striations (similar to the 1981 Soldier). This is the last year for the matte Wenger blades, and the stamped dates have a box around them, so it appears that Wenger may have been fiddling with their manufacturing process. Tools continue with some minor changes, on the subsequent 1983 Soldier.
