Use: The lark's head is a knot (specifically, a hitch). Also called a cow hitch, it comprises two half-hitches tied in opposing directions. The cow hitch is often used to connect loop-ended lanyards to handheld electronic equipment, since it can be tied without access to the ends of the fastening loop.

How to tie:

When both the standing parts of the rope are available, the cow hitch can be tied in the following manner:

1. Form a bight and pass it through the ring from the underneath.
2. Pull the head of the bight downwards, and reach through it, grabbing both standing parts of the rope.
3. Pull both standing parts of the rope through the bight.
