Ashley's stopper knot, also known as the oysterman's stopper, is a knot developed by Clifford W. Ashley around 1910.
 It makes a well-balanced trefoil-faced stopper at the end of the rope, giving greater resistance to pulling through an opening than other common stoppers.
 Essentially, the knot is a common overhand noose, but with the end of the rope passing through the noose eye, which closes upon it.

 It is the result of implementing a double wall knot in one strand.
