Here is a simple lanyard I made for a customer. The core is removed from the loop so that the lanyard can be fed through the lanyard hole on many folding knives. This one has a nice silver Starlingear skull between 2 lanyard/diamond knots.
Here is a cool lanyard with a survivalist undertone. Concealed within the cobra stitch is a ferrocerium (fire steel) rod that can be removed and used to start fires in an emergency situation. Topped off with an Emerson pewter skull, this setup makes for a stylish yet effective survival lanyard.
