A look at four pocket multi-tool bottle openers; the Leatherman Micra, IDL Tools T-10, Gerber Shortcut and a Victorinox Huntsman Swiss Army Knife. We used each bottle opener on a standard beer bottle cap. All openers work, but the smaller tools take more than one attempt to pry the cap off the bottle. The larger tool on the Victorinox Huntsman easily opened the bottle in one motion.
