My Father in Law made this lucet for me out of Jarrah (an Australian wood which is very hard and has a fine grain). He smoothed it with a very fine sandpaper and used beeswax to polish the surface so that it is nice to handle and the yarn will slide over the surface of it easily. It still needs a hole at the base of the handle. A lucet is used to make cord with a square cross-section. I'll take another photo once I've made some cord.
