Hatsukokoro Kumokage Kurouchi Damascus Gyuto 210mm


Hatsukokoro works with a wide variety of Artisans Just outside Osaka Japan, from blacksmiths, Hande makers and Master knife sharpeners. The Kumokage line is Hand-Forged with Aogami 2/Blue Carbon 2 Steel cladded in Soft Iron. The knives are really well made, have nice even grinds and really well balanced.
Blue carbon steel is known for its amazing edge retention and sharpness. The knife is fully reactive carbon/Iron so some extra care is required. Make sure that you avoid “bad” rust (Orange in colour) from forming on the blade. Wash the knife with soapy water after use and make sure to dry it properly with a paper towel or dry cloth. Over time, the blade will begin to develop a Patina “good” Rust. This oxidation will usually be grey to dark grey in colour and actually protect your knife from harmful rust. The knife will slowly start building its own personal character.



Gyuto (Chef’s) Knife (牛刀包丁 – pronounced: Gyūtō Bōchō) literally translated from Japanese means ‘Cow Blade’. ‘Gyu’ means Cow and ‘to’ means blade. The name stems from its original use to slice and disjoint large cuts of beef. These days the Gyuto is comparable to the Western-styled chef knife and is viewed as an all-rounder in the kitchen.

The Gyuto is the ultimate multi-purpose kitchen knife and is perfect for chopping, slicing, mincing and dicing boneless meat, fish, vegetables, fruit and herbs. The blade profile is well suited for tap-chop or thrust-cut. The slight curve from the middle of the blade leading to its pointed edge is used to rock-chop. Its name also suggests that it is perfect for cutting meat and doing light butcher work. It can be used to pull-cut softer meats or to push-cut more muscular cuts of meat.

The Gyuto features a longer blade providing versatility for cutting larger produce while the tip of the blade allows it to be nimble enough for precision work. The edge is flat from the heel to the belly with a slightly rounded profile from the belly to the tip. The hard steel used in manufacturing makes the double-bevel edge much sharper than Western chef’s knives and retains the ultra-sharp edge for much longer.

Care Instructions

  • Wash and dry the blade by hand immediately after use. Dishwashers are very bad for all knives.
  • Use a soft cloth to wash the blade. Avoid abrasive dish scrubbers and powders as these can damage the finish of your beautiful knife.
  • Do not cut through bones. You can certainly cut along/beside bones, but do not cut into bones. This can, at worst, chip the blade.
  • Never use this knife to cut frozen food.
  • Never twist or cleave the blade.
  • Always use a wooden or plastic cutting board. Never cut on bamboo, glass, marble, slate, a plate, china, marble, arborite or anything harder than steel.
  • Store knives in a way that the blades will not knock into each other.
  • Never transport knives unprotected.
