The knife and its tools are almost always a better guide to the age of the knife than the box. In my research, the box age is almost secondary - i.e. "this is a box from the mid 80s because it's with a knife from the mid 80s" rather than vice-versa.
Here are some boxes from an
active eBay auction:
Boxes here are, with approx dates, clockwise from the upper left:
- Burgundy Victorinox box, mid 80s to mid 90s
- Marlboro, early 90s, typically a cardboard surround over a burgundy box
- Old style silver Victorinox box, mid 90s-early 2000s
- Burgundy, as above
- Black/White Victorinox box. I think this is a non-US (i.e. non-SAB) early- to mid- 90s box.
- Old style silver Victorinox box, as above
- New style Victorinox box, early 2000s - present
- New style Victorinox box, as above
- Black/White Victorinox box, as above
- SAB Grey box. Late 80s- mid 90s SAB (US distributor) box
- SAB Box, as above
Then there this one, red early 1970s - mid 80s box:
You see a lot of these from the early 1980s.
