This is a very old iron tsuba. It's made of well-forged iron and has a very nice texture. It's a fairly large tsuba, but it has an unusual construction, gradually thinning from the ear area towards the center. It's an iron tsuba with a beautifully balanced design. I believe it's a very old piece. 8.6 cm × 8.4 cm × 4.2 mm (ear area) 2.0 mm (seppa dai area)
