Usuba is a single beveled blade (right-handed users only!) designed for chopping vegetables. It is one of the "holy trinity" of Japanese classic kitchen knives for sushi preparation. The length of the blade is 165mm (6.5").

The rectangular blade consists of 2 layers of steel - the harder steel AUS-8 (58 HRC) and a layer of softer stainless steel (SUS405) are forge welded together in what is known as "nimai" construction. The knife is very easy to maintain and great for grinding on water stones.

The knife has a minimalistic polished blade and is fitted with a traditional japanese (Wa) handle made of Rosewood with a darker wood ferrule.

Suitable for first-time buyers of a Japanese kitchen knife. It can also serve as a wonderful gift!

The steel used for the blade of this knife was madein Aichi Steel Plant, Japan. This is an entry grade Japanese steel used in manufacturing kitchen knives. The AUS-8 has slightly less carbon, is rust resistant, excellent for sharpening. Hardness around 58 HRC, meaning it is a slightly softer steel, but of high quality nontheless.

Composition: Carbon (C) 0.7-0.75%, Chromium (Cr) 13-14.50%, Vanadium 0.10-0.26%, Molybdenum (Mo) 0.10-0.30%

Where the blade meets the handle, you may notice a special feature called Machi spacing. This is a small gap between the lower part of the blade and the handle, which can be seen mostly in Yanagiba knives. It is a feature that pays tribute to Japanese swords and is typical mostly in the work of blacksmiths located in and around the Tokyo area. So don't worry, it is not a flaw in assembly of the blade and the handle, but rather a homage to japanese forging tradition that could be displayed on a magnet right there on your kitchen wall. :)
