|Names||Diamond knot, Knife lanyard knot|
The diamond knot begins as a carrick bend with the ends exiting diagonally opposite each other.
Each working end is then passed over the other rope's standing part.
Then the ends are passed up through the center of the carrick bend from below. The knot is then gently rearranged and tightened so that the ends emerge from the knot parallel and opposite their own standing part. To finish the knot is further tightened by carefully working the slack out towards the standing parts and ends.
