The 1967 Soldier Swiss Army knives are a 93mm / 3 1/2" ribbed alox knife, with a 1967 date on the blade tang. This model was standard issue for the Swiss army during 1967. It has a cutting notch in the bottle opener, a hollow rivet, Elsener Schwyz on the blade tang (Victorinox only), a cross with Waffenkontrolle stamp instead of the insignia. Some knives have Pat stamped on the can opener, and some do not. The tools are similar to the 1966 Soldier, and the subsequent 1968 Soldier. We have only seen Wenger knives for this year, and it is possible that Victorinox skipped it.
