This knife makes the rounds about once a year. It is a demo showing off all the tools that are possible. It would appeal to the collector...might appeal quite a lot if you were a Wenger collector (pretty sure this is a Wenger). I believe that Victorinox makes one not at all unlike this one with their version of all the tools.
Dealers and collectors, not hikers or bushcrafters, are going to be your buyers on this thing.
I have always wanted the Swiss Champ, the Victorinox "do it all" SAK but it is just too big to carry...but maybe someday. It, at least, is really intended as a tool, something you'd carry in a backpack or an bug-out bag or maybe a glove compartment. It is a real tool if not a particularly practical one.
