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. However, you could loosen the two set screws, remove the Hitchhiker, loop the cord through your knife, and then reinstall the Hitchhiker. This gives you more cord to loop through larger, non Gear Infusion tool.
You can absolutely use the cord for added grip, even when using the bottle opener version.
