Fisherman’s Knot is an essential knot to know for camping, climbing, fishing and for general purposes. I use this quite often to attach two lines together for those times when I’m just short of line. It’s easy to tie: Basically tie an overhand knot with each line to the opposite line. Pull the lines apart and the two knots lock to each other.
