Dear Gordon, I'll start asking around. I have concentrated on the wire rope work and the rigging used but off the top I'd say the only fiber line I see used is very limited. Every feller (the guy with a saw who knocks the trees down) and bucker (the fellow who follows the feller and makes the trees into measured lengths... often the same man) carries two one gallon plastic jugs as well as his saw, wedges and pole axe. One jug has lubricating oil for the saw bar/chain. The other has gasoline/oil mix for the twocycle engine on his saw. These he ties together with a loop of 1/4" nylon "clothes line" so they can be slung over his shoulder. The loop is bent on with any "knife knot" as I don't think one in 50 can tie a good bend and most have found out that the reef knot isn't a bend for this task. I see many ABOK #1410 used. All carry a small backback (daypack) with rain gear, food, water or coffee (if he doesn 't mind the weight of the vaccuum bottle) gloves, socks, some limited personal choice mostly a pocket knife and a little flash light (torch to you?). Nobody wears a pants belt but most carry some more 1/4" line, which might make a belt over the rain gear on a really horrible day. You can spot a man in the woods by the cloud of steam rising off him so it has to be really bad weather before he gives up the ventilation of beltless pants. He ties his belt with a slipped granny or a slipped reef knot. He has no name for either. There is very little cordage involved. If something needs to be tied out of the way or secured to the rig almost all know some variation of a Trucker's Hitch, but I don't think they refer to it by any name. I'll make a real point of asking over the next few weeks and will post back when I have some answers. These are rough and tumble men, not a single pocket knife has a point on it. All tools and gear is "expendable". They work horribly hard, leaving home in full darkness to be on the job (often several hours from home) before first light. They work until it is too dark to do so safely and hump out of the bush by feel. But when we get to the wire work almost everyone can do all that is required and very nicely at that. These guys get hurt pretty often and while healing get to work the softer jobs that don't require instant mobility. Soft jobs include splicing wire. What a life!
