First of all what have we got on a lanyard and where? If it is something carried around the neck (knife,compass,flashlight etc.) I would NEVER use any manner of cordage. I do carry my neck knives under clothing, so the possibility of hanging myself is reduced. That small diameter can inflict nasty tissue trauma even with a breakaway. I use LAMPWICKING, the cotten webbing used in oil and kerosene lamps. It is available in large rolls from
www.sirmailorder.ca/ in Canada. I just put a few single stitches FLAT end to end and make sure it always rests anterior to my good looks <img src="images/graemlins/tongue.gif" alt="" />. Lampwicking has the additional happy quality of becoming tinder in emergencies.
