The Victorinox Waiter Plus is a single layer 91mm Swiss Army Knife. Very similar to the 84mm Waiter, it adds a couple tools to the scales, and the mini-screwdriver in the corkscrew. Quite a few tools for a slim knife. This model appears to be the only single-layer knife with a 91mm frame size. There may be other historical or advertising models though.
