This is an Aritsugu yanagiba knife. The blade length is approximately 23cm. The steel type is unknown, but it's probably Shirogami (white steel). The handle is a buffalo horn handle. The rust and scratches have been repaired and mirror-polished. Some minor scratches and rust marks remain, but it's in a beautiful condition. The handle was corroded, so it was replaced with a buffalo horn handle. With a blade length of 23cm, it's easy to use, and the condition is also beautiful, so I think you can use it for a long time. Both the cutting edge and the flat surface are almost mirror-polished. It's also lightweight and is recommended for professionals and general households. The sharpening stones used for finishing are Kitayama 8000 grit, Shapton 12000 grit, and a natural whetstone. It's in a very sharp condition, so you can use it immediately. ● Size: Blade length approximately 230mm ● Blade thickness: Approximately 3.7mm at the thickest part of the base of the blade ● Overall length: 375mm ● Weight: 139g #Knife #Yanagiba #Aritsugu #23cm
