Neck lanyards for knives and other gear is a convenient option. The cordage of choice is usually paracord. This gives us a convenient bit for emergencies. It does have the disadvantage of potentially garroting the user :shock: . I have been using Lampwicking as used in oil lamps. This makes a very comfortable lanyard and can be sewn with a breakaway. the stuff is also superb emergency tinder. My source is www.sirmailorder.ca/ You may have to email to get a current quote. It is sold in very generous rolls. This is the stuff used in traditional snowshoe bindings and is usefull for many projects.
