I've been having fun with the Wengers. I just went through the adventure of finding the odd Master variant I got in a bunch of SAKs... Now, another of those knives just sent me digging... It's a large SAK, with some odd tools... I ran through all the usual suspects, Tool Chest/ToolChestPlus, Monarch, Motorist... None matched...
The closest match I can find is the Matterhorn Plus,
if you lose the Ruler/Compass. Don't know if this is just an older version of that model, or what... The oldest catalog I can find is 1991, so...
Those Wengers... An adventure in/of themselves.....
