The Masamoto KK Usuba kitchen knife with a 210 mm blade is sharpened with a single bevel, and can be considered the equivalent of a Western Nakiri knife. However, unlike the Nakiri, it has a thin blade, which makes chopping and cutting vegetables much easier.
Masamoto Sohonten was founded by Minosuke Matsuzawa, who has been specializing in knife production since 1872. At the beginning of his career, he set himself one goal: He wanted to create a brand that would be synonymous with excellent quality. After many years, it must be said that he has managed to fulfill this dream, as Masamoto kitchen knives are now considered among the best in the world. The successful Masamoto KK Kasumi series also showcases this high quality, featuring durable knives with a double-layer blade. Their core is made of carbon steel called Shiro-ko #2 – White Steel No.2, and the outer layer is made of soft steel. It is worth noting that they are hand-forged and finished. In addition, thanks to a special heat treatment, the blades achieve a very high level of hardness, reaching up to 62-63 HRC. Traditional Japanese-style knives also remain exceptionally sharp for a long time. They can be recommended in particular to demanding sushi masters and enthusiasts of Japanese cooking who enjoy sushi. The D-shaped knife handle is made of beautiful magnolia wood. Additionally, it is decorated with an aesthetic finish made of a ferrule, which is produced using buffalo horn. Due to the fact that these are not stainless knives, it is important to remember to care for them properly after each use. An interesting fact is the origin of the name of the entire collection – Kasumi literally means “mist” and “fog.” This refers to the unique finish that characterizes each laminated knife in this series – it brings to mind “mistiness.” The aesthetic boxes in which the kitchen knives are stored can be treated as ready-made gift packaging.
