The double sheet bend is ideal for joining ropes of equal or unequal diameter, joining wet ropes, or tying a rope to an eye. It will not slip or draw too tight under heavy loads. Not surprisingly, this knot is more secure than the single sheet bend, especially when used in a spliced eye.
HOW TO TIE:
1. Form a bight, or a curve, in the thicker rope and hold it in one hand.
2. Pass the thinner rope through the bight and behind the tail and standing ends.
3. Tuck the smaller rope under itself to finish the knot.
