The Ranger Swiss Army knife is the smallest of the really big multi-tools from Victorinox (or the largest of the "average sized" knives, depending on your perspective).

This model contains five rows of tools. It's almost an inch thick (23 mm), so you'll probably want to carry it in a backpack or on a belt pouch, rather than in your pocket. When it first came out, this model was also called the Garden Ranger.
