Not Swiss, but Interesting to study. Looks similar to some older Wengers. What I find most interesting is that it uses brass, stainless, and carbon steel. Only the main blade is stainless... and in this case provides a striking contrast to the other heavily rusted implements. However because of the brass liners all the tools still open relatively smoothly and there are no broken springs. Needs a good cleaning, but that might further damage the scales which have had a fair amount of shinkage.
