AY Honors/Knot/Slipped half hitch
From Pathfinder Wiki
Use: A slipped half-hitch is a knot used to attach a line to a rod or bar. It does not provide great strength compared to some other knots, but it can be tied relatively quickly and released very easily. These characteristics mean that it is used on square-rigged ships for securing the gaskets that bind stowed sails to the yards.
How to tie:
WARNING: Never use this knot in a critical situation. It comes untied at the slightest provocation.
