These Canada made Lanyards have a glow in the dark fobs. These look great on tactical and utlity folders, are great for finding them in the dark and add an extra 2 to 3 inches of collapsible handle grip to your knife. To install this you simply push the closed end through your lanyard hole and then loop the lanyard base through it and slide the small skull to lock the slip knot. If your knife's lanyard hole is on the small side you could still use a small keychain loop to attach these but the special small gauge para cord the maker uses on these should fit through most holes with a paperclip hook and a little mineral oil or whatever's handy.
