Used to secure a rope to a pole, or to start or finish a lashing. Pass
the running end of the rope over the pole twice. Then pass the running
end over the standing part of rope, and tuck it back up and under itself,
forming a half hitch. Repeat this for a second half hitch.
This knot has a redeeming feature - it rarely jams!
Tip. Superior to a Clove Hitch for starting
and finishing a lashing as the half hitches prevent this knot from unrolling,
as they have the effect of locking the knot. The Clove
Hitch looks neater (!) but it has a tendancy to unroll, and can be
difficult to tie tightly when tying off.
