I just run a bit of the cord through the attachment point on the object. I form a loop with the cord. I keep enlarging the loop until I can comfortably stick my hand through the loop. Then I just tie a simple overhand knot. Then I cut the cord and burn the ends to keep it from unraveling.<br><br>I used to use climbing accessory cord before I found the reflective guy line. 3mm climbing accessory cord has a breaking strength of 2250 lbs or something like that. It is available in a variety of bright colors. I then would put a wrap of reflective tape on the cord. I would also put some reflective tape on the object.<br><br>So far the only objects that have lanyards are knifes, multi-tools, MFS, and Boy Scout Hot Spark. I rely on the reflective tape to locate dropped items.<br><br>A double fisherman knot might be a better knot but the overhand seems to have worked so far. The advantage would be the loop could be tighened after the hand is entered.
