This is a Usuba knife from Masamoto Sohonten. The 21cm Usuba knife made of Tamahagane steel seems to be sold for around 45,000 yen. It's likely an unused item without a sharpened blade, and the overall condition isn't bad, but there are some dull spots, rust marks, and minor chipping on the blade. 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.
