A Shroud knot is a way of joining two ends of rope together. The individual strands of a twisted rope are knotted, but not woven, to the individual strands of another twisted rope. This makes it more secure than a simple bend but less secure than a full splice.
Shroud knots were originally used as a quick way or repairing a rope that had broken aboard a ship. As modern ships now use steel cable for the most part, the knot is now more often used decoratively than functionally.
