A lucet is a tool used in cord making or braiding which is believed to date back to the Viking and Medieval periods, when it was used to create cords that were used on clothing, or to hang items from the belt. Lucet cord is square, strong, and slightly springy. It closely resembles knitted I-cord or the cord produced on a knitting spool. Lucet cord is formed by a series of loop like knots, and therefore will not unravel if cut. Unlike other braiding techniques such as kumihimo
, finger-loop braiding
, where the threads are of a finite length, lucetted braids can be created without pre-measuring threads and so it is a technique suited for very long cords.
