The handful that do everything, tied properly.
Bowline
Knots and Rope
The loop that will not slip and still unties after it has been loaded.
Clove hitch and timber hitch
Knots and Rope
Two quick hitches for poles and logs: the clove hitch to tie off to a post and start a lashing, the timber hitch to drag a log out of the woods.
Coiling and caring for rope
Knots and Rope
Coiling a rope so it comes off clean next time, sealing the ends, keeping it dry, and knowing when a rope is done.
Joining two ropes
Knots and Rope
The sheet bend for a quick join that unties easily, and the double fisherman's for one that stays put.
Knots that do everything
Knots and Rope
Four more knots and you can rig near enough anything.
Tarp lines and lashings
Knots and Rope
Getting a ridgeline tight and a load tied so it stays tied.
Trucker's hitch
Knots and Rope
The rope pulley that cinches a load, a canoe or a ridge line drum tight and still lets go when you want it to.
