We crimp the lanyards with a metal barrel crimp first, and then the two set screws clamp down onto that crimp so everything is locked in place.
Right now, we only offer the Hitchhiker lanyard in one size, which is designed to fit our EverRatchet and GhostTi tools. However, if the loop isn't long enough for your tool, you can loosen the two set screws, remove the Hitchhiker, loop the cord through your knife or other tool, and then reinstall the Hitchhiker. This gives you additional cord length, making it easier to attach to larger, non-Gear Infusion tools.
You can absolutely use the cord for added grip, even when using the bottle opener version.
