This is a Usuba knife from Shomasa Sohonten. The steel type is unknown, but a 27cm Usuba knife seems to be quite expensive. It's likely unused and hasn't had its final sharpening, but there are some dull spots, rust marks, and minor chipping on the blade. It also appears to have a slight warp, so the price is set lower. It can cut to some extent, but it's recommended to sharpen it before use. Please understand that this is a used item, and only purchase if you are comfortable with this.
