Aoi Art's Comment: Raikunitoshi's works are particularly noted for their beautiful Jitetsu, which has a blackish tinge and visible landscapes within the steel when observed closely. The Hamon is a straight line but includes fine details like small feet along the edge, and the presence of Nie creates reflections, indicating an exceptionally high-quality creation. This piece is highly recommended.
