This is an Aritsugu yanagiba knife. The blade length is approximately 24cm. The steel type is unknown. The handle is a buffalo horn handle. It has a special engraving. The steel of the cutting edge shines beautifully after sharpening. I polished the flat and cutting edge, resulting in a near-mirror finish. The shape of the yanagiba knife and the balance between the cutting edge and the flat surface are also beautiful, which is what you'd expect from Aritsugu. I repaired rust and scratches, but some rust marks (pitting) remain on the cutting edge. I recommend it if you don't mind. It's generally clean and a user-friendly size, so I recommend it for both professionals and home cooks. It has been finished with a Kitayama 8000 grit stone, a Shapton 12000 grit stone, and a natural whetstone. It is in a very sharp condition and can be used immediately. ● Size: Blade length approximately 240mm ● Blade thickness: Approximately 3.6mm at the thickest part of the base of the blade ● Overall length: 385mm ● Weight: 137g #knife #yanagiba #Aritsugu #24cm
