The Sheepshank Knot is used to shorten a rope or isolate a damaged section without cutting it out.
But let’s be honest: it’s not exactly one of the most reliable knots.
It can fail when there’s no tension in the rope or when used with modern synthetic ropes like Nylon.
So, why bother learning it?
Well, it’s a classic knot, and if you’re in Boy Scouts, you must know how to tie this knot.
Let’s learn it in detail.
Sheepshank Knot Details
Type: Scouting
Other Names: Trumpet Knot
ABoK Reference: #1152, #1153, #1154
How to Tie a Sheepshank Knot
- Make two opposite-facing bights with your rope.
- Make an underhand loop from the slack in the rope.
- Feed the bight through the loop on the left and the right.
- Pull both ends to tighten the knot.
For a more secure Sheepshank, use the Marlinespike Hitch at either end of the rope instead of Half Hitches and seize the ends to lock it in place.

The Sheepshank knot is used for
