Locking pliers that fold away make the Leatherman Crunch unlike any multi-tool available today. The Crunch clamps up to a 1-inch diameter pipe, and if you remove the adjusting screw, you'll find a hex-bit adapter built right in. With locking blades that release with the push of a button, the Crunch will take a bite out of any job.
All locking features means that every tool and knife on the body of the handle, with the exception of the plier head, will lock into place. Note that the Crunch; however, does feature both all locking tools and plier head. The all locking design enables the user to operate individual tools safely and effectively. By locking them into place when fully open, the user can put pressure on the implement while safely completing the job, before manually unlocking the tool to stow it away.
This secure ring is for attaching the tool safely and securely to a lanyard. Often people who work near water or on scaffolding attach their tool to a lanyard on their person to avoid losing the tool if it's dropped.
