Used when stringing a bow in Japanese archery (kyudo). Material: Katsura (Japanese Judas tree, a relatively soft wood) Surface: Colored (rose pink) and coated with glossy transparent synthetic resin Dimensions: Length 90mm, Width 45mm, Thickness 20mm Made by hand by a husband who worked for a furniture factory for 15 years, at the request of his wife, who is a 5th dan in kyudo. This is one of several he made. His wife wanted to fix it at a height taller than herself, so screw holes have been pre-drilled in the four corners. The trapezoidal groove is hand-finished with a chisel. It's a shape that can't be carved by machine. Screws are included, but installation and fixing are at your own risk. The photos emphasize the gloss and show a brighter color than the actual item. Please be aware of this.
