Higashiho Forging's Yanagiba knife, blade length is 20cm. Total length is 34cm. Thickness is not specified. "Higashiho Tokusei (Special)" is engraved on the back. The steel type is unknown, but it appears to be some kind of steel as it rusts. The blade has a slight warp to the left (photo 5) and a small chip (photo 8). There is rust at the border of the handle and blade (photos 6, 7). Thank you for viewing.
