The Victorinox Executive Alox Swiss Army knife is a compact version of the popular Executive knife that is housed in a light aluminum alox shell. It probably has the maximum possible quantity of useful blades per ounce of knife (or per gram of knife, if you measure in metric!)

This model is no longer in production, but it is sometimes available as a used Swiss Army knife. Alox Executives will soon be collector's items, and they already command a premium price.

Ambassador Alox-- no key ring, small blade or orange peeler/scraper
Executive-- same tools in plastic shells, adds toothpick and tweezers
