this pouch is for the 84mm and 58mm classic range from Victorinox and the biggest knife from that range the minichamp fits well, but note this is NOT a belt pouch, its just a storage pocket pouch to protect your knife from scratches and from being beaten up by other stuff in your pockets.
Fits any 84mm knives, but only up to 2 layers (pocket knives that fit this pouch - bantam, recruit, small tinker, cadet alox, sportsman, tourist, waiter, alox bantam).
A bit tight at first for some of them, but the leather will stretch after a while.
Another note is that it will may NOT fit the 58mm midnite minichamp that one is too thick coz of the led light in the handle.
Edit: these pouches don't have the Victorinox logo, but they are the real deal, just look at the online Victorinox catalog.
