Hi Seisaku refers to the traditional craft of making wooden weaving shuttles—tools that carry weft yarns through warp threads on a loom. Finish-quality hardwoods like dogwood or boxwood are shaped and hollowed into sleek “boat” designs or simpler stick forms. Shuttles are carefully sanded and polished to minimize friction, with cavities elegantly carved to hold yarn spools snugly. Often featuring aesthetic touches like laminated woods, these meticulously crafted tools blend function and artistry to ensure smooth, efficient weaving.
