The Swiss Army Knife is likely the most recognizable multitool in human history. Sure, it may not be as functional as the Gerber MP600 that’s standard issue for American soldiers or as daunting as the Chinese military shovel, but the legendary pocketknife is a necessity for opening MREs, cutting 550 cord, and a billion other small tasks that may arise on the battlefield. It cuts, it clamps, it screws and it tweezes — it won’t save your life, but it’ll make life a hell of a lot easier.
