This is a multi-purpose Japanese kitchen knife, suitable for use at home, as well as in a professional kitchen. Gyuto, or Chef's knife, is a versatile kitchen knife that will shine with all kinds of chopping, slicing and rocking motions on the kitchen board.
The top part of the blade features dents from the hammer, which have been polished to a high polish. At the bottom of the blade we can see a very pronounced, curvy line that goes along the entire length of the blade. This is the line between the core and the two softer, outer layers of steel that serve as additional protection of the core steel. Such sandwich of the harder core steel and softer outer steels is called san-mai clad, most of today's Japanese knives are made this way.
This Gyuto was fitted a yo-style, Western-type handle made of pakka wood, and features a stainless bolster. The knife tang ends halfway through the handle, further reducing the weight of the knife and pushing the balance more towards the tip of the blade, like with Wa-style, traditional Japanese handles. The handle will fit well in your hands for both the hammer and pinch grip.
The blade consists of 2 layers of steel - the harder steel AUS-8 (60 HRC) and a layer of softer stainless steel are forge welded together in what is known as "nimai" construction. AUS-8 steel is a popular Japanese steel from the Aichi steelworks that is incredibly resistant to rust, yet simple to sharpen. The steel contains high amounts of carbon (0.7-0.75%) and is also high in vanadium (0.10-0.26%) and molybdenum (0.10-0.30%). It also has a high percentage of chromium (14.5%), making the blade corrosion-resistant and increasing the hardness, durability and the tensile strength of steel mix.
This carefully balanced composition does not only endow the blade with exceptional hardness (60 HRC) but also good wear and tear and rust-resistance properties.
→ Long lasting sharpness: 60 HRC hardness and high carbon content make the blade razor-sharp and help it retain its edge for a very long time.
→ Rust-resistance: due to high chrome content (14%), the steel is very resistant to corrosion. Even so, you should not skip any of the steps of blade maintenance: wiping it with a dry cloth after use and storing it correctly in a dry and safe place are important steps for prolonging the service life of your knives.
→ Wear and tear resistance: the composition of this steel mix also makes the blade very resistant to wear and tear.
Due to the choice of materials and precise final treatment of the blade by hand, the blade is simple to maintain, retains its edge for a very long time and is perfect for sharpening on water stones.
Suitable for first-time buyers of a Japanese kitchen knife. It can also serve as a wonderful gift!
