Leatherman Crunch Multitool with Sheath Locking pliers that fold away make the Leatherman Crunch unlike any multi-tool available today. It's like carrying a vise with you. Clamps up to a 1" diameter pipe. Remove the adjusting screw and you'll find a ¼" hex-bit adapter built right in. Locking blades release with the push of a button.
