Form a loop in the rope. Pass the end through it. Pass the end through the loop again. Tighten the knot to make a secure stopper knot.
Uses: The Double Overhand Knot (ABOK # 516, p 84) is based on the Overhand Knot with one additional turn. It creates a reliable, moderately large, stopper knot.
Alternative Method: In addition to the technique shown in the animation, the Double Overhand can also be tied by threading the end of the rope through the coil as shown here.
The Double Overhand Knot provides the basis for tying other useful knots such as the Double Fisherman's Knot and thePoacher's Knot or Double Overhand Noose.
Uses with Other Knots: In addition to acting as a stopper knot in the end of a rope, the Double Overhand Knot has another use; itcan also be used to increase the security of another knot:
Other Stopper Knots: The Figure 8 may be the most widely used, especially in boating, but it tends to come undone. TheAshley Stopper Knot deserves to be more widely used and known. The Matthew Walker requires three or four strand rope because it is tied with the separated strands. Therefore, after the strands are reassembled and whipped it cannot be just "untied". Its greatest use may be in smart installations such as rope handrails.
