I got today this Wenger Profi, older 95mm long knife.
Mine specimen is dated 78, but the overall design screams 60' to me - the rounded hexagonal scales, large exposed rivets. Per SAK wiki this is model 1.72.21, toolset is similar to Victorinox Rancher - blade, bottle opener (with 90° stop, but not very strong), inline awl and pruner blade.
I really like certain details of the knife - the inscription Wenger Profi on the bottle opener, the extra large rivets, the wave-like shape of the wide keyring nub.
On the other hand, you can tell the quality of the knife is not that great. My knife seems to be unusued (no visible wear or scratches) but the main blade has some sideplay and although the bottle opener/screwdriver is very solid, I would not use too much torque on it - the knife has only one outer liner, on the other side (where the bottle opener is located), there is only the plastic scales. Given the name Profi, I do not think it was the greatest decision. As well, the nail nick on the pruner blade is not easy to reach and when the pruner blade is closing it sometimes stuck across the main blade.
The rivets on the non-liner side are significantly larger than on the liner side - I assume to prevent tear out through the plastic. I wonder why they decided for this construction - probably cost cutting? But how much you can save on one liner with negative implication on the usability of the product?
Nevertheless, despite the quality issues, I like the knife, looks very cool to me and it is interesting piece of SAK history.
