I'm Hiroshi Nakagawa, a Japanese woodworker.
I manufacture and sell wooden polyhedra for teaching materials.
I call the method of making a regular polyhedron the cube chamfer method. See 'Wooden Polyhedra English edition' for more information.
I always try to create accurate and beautiful wooden polyhedra.
