Plural of 'becket': a nautical rope loop or grommet used on ships to hold rigging, sails, or other equipment in place.
Of uncertain origin, possibly named after an inventor or derived from the shape; first documented in maritime vocabulary in the 17th century. Beckets became standard equipment on all sailing vessels.
A becket might be small, but it's one of those inventions that's so useful nobody bothered to invent something better—sailors have been using the same design for 400 years!
