This is an older version of the Victorinox Huntsman. It’s probably from the 1970s. It features the long nail file on the back side of the scissors layer. That tool has been out of production for years. Unfortunately this one has a broken tip.
When this particular knife was sold it was probably known as model no. 236 aU, but that could also be the identifier from longer ago when the awl was still the thick triangular one.
