The Hatsukokoro x Nigara Irodori aogami#2 damascus kiritsuke gyuto is a handcrafted Japanese knife forged by Nigara Hamono for the Hatsukokoro brand. Based in Aomori, Japan, Nigara Hamono forged this blade using a core of Hitachi aogami#2 steel, known for its excellent balance of edge retention and toughness.

The blade showcases a striking damascus pattern with bold geometric patterns and angular shapes, etched to accentuate the contrast between the damascus cladding and the Aogami#2 core steel. Its spine is chamfered, exposing the intricate damascus layers. This knife employs a stainless cladding, sandwiching the carbon steel core for easier maintenance. Only the exposed edge will be reactive. The blade is paired with an octagonal walnut handle, accented by a horn ferrule.

A 270mm gyuto is ideal for those who prefer something longer than the usual 240mm chef's knife. This extended length excels at handling larger ingredients and is favored by professionals and home cooks who appreciate extra cutting edge. The kiritsuke profile of this gyuto is well-suited for those who prefer a flatter profile, enhancing push-cutting techniques and precise slicing. This longer blade offers increased versatility for a wide range of kitchen tasks, from breaking down large cuts of meat to efficiently processing volumes of vegetables.

Care Guide
  • Use a whetstone to maintain sharpness. Avoid electric sharpeners and pull-through sharpeners, as they are not suitable for Japanese kitchen knives. Honing rods, typically used for western-style knives, may potentially damage the edge.
  • Choose a wooden or rubber cutting board instead of bamboo or poly boards to preserve the knife's edge.
  • Keep the knife clean and dry, especially if it is made of carbon steel. Carbon knives are prone to rusting.
  • Avoid using the knife to cut through bones or frozen foods. It's best to use a separate knife specifically designed for these tasks.
  • When cutting, use a smooth and fluid motion, avoid twisting or torquing the blade. This technique helps maintain control and minimizes the risk of damage.
  • Never put Japanese kitchen knives in the dishwasher. Instead, hand wash them with mild soap, ensuring thorough cleaning, and then dry them completely before storing.
