How to tie Shear Lashing (or Sheer Lashing). Shear Lashing is a knot used to bind two poles together. It is also useful as a solution to repair or reinforce a broken pole, add a section of reinforcement to strengthen a weak pole or to create an A-frame by spreading the two poles apart after the knot is completed.

Shear Lashing Knot Tying Instructions
Tie a Clove Hitch around one pole and pull the knot very tight.
Begin the lashing by wrapping the working end around the poles, pulling the rope tight on each turn, until your lashing is at least as long as the two poles are wide.
Make a turn around just one pole.
Tuck the working end between the two poles.
Make 2 "frapping turns" (wrap around just the ropes, between the two poles) and pull tight.
Finish with one or two clove hitches around the same pole that started the lashing.
Optional: To make "Shear Legs" for an A-frame, follow the same steps, but make the wraps a little less tight to allow for movement when the poles are spread apart. Once the Shear Lashing is complete, pull the legs apart and adjust for tension and stability.
