The Hado Sumi chef's knife has a 240 mm blade and is versatile for various types of kitchen work. It is perfect for cutting large pieces of meat and chopping.
The Hado Sumi kitchen knife collection is known for its handcrafted production process. Yoshikazu Tanaka is responsible for forging the blades, while Tadataka Maruyama is responsible for finishing and sharpening each one. These knives have a core made of carbon steel called Shirogami #2 (also known as White #2), surrounded by special soft iron cladding. The unique, raw appearance of the black blades is due to a special type of Kurouchi finish. The hardening gives them a high degree of hardness, in the range of 62-63 HRC. As a result (and thanks to the heat treatment of the steel), each knife in this series is easy to sharpen and has the added advantage of maintaining its sharpness well. The beautiful, octagonal handle ensures great comfort during kitchen work. Oak wood is used to make it.
All Hado kitchen knives can be recommended to the most demanding users – both professional chefs and amateur cooks who appreciate Japanese craftsmanship. Please note that, as these knives are not stainless, they must be dried after each use.
