The Handywoman Lucet tool is made from solid wood and will be available in a variety of different species depending on the demand for these lovely old world tools. The handled style is a little over 6" x 2" and the lucet without a handle is approx 3.25"x2".
They have recently made a come back as people are wanting to recreate the past. I hope you find my lucets pleasing and fun to use. 
A little info and history of these lovely tools:
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 or plaiting, 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.

Archaeological finds and a literary description of lucets strongly suggest that its use declined after the 12th century, but was revived in the 17th century. Its use waned again in the early 19th century.
