This is a yanagiba knife with a mirror-polished surface. It appears to be a hon-yaki knife, but the details are unknown, so please judge from the photos. It has a black ebony handle with a water buffalo horn bolster and comes with a saya (sheath). I am selling it to organize my collection. Please check the photos carefully and purchase only if you understand. Yanagiba knife Blade length: 210mm (7 sun)
