A 180mm KS honkasumi kamagata usuba from Masamoto Sohonten. The KS series, a popular choice among collectors and culinary professionals alike, features a high-grade shirogami#2/white#2 core steel and a higher level of refinement compared to the KK series. Heat-treated to 62-63 HRC, this steel excels in attaining remarkable hardness without excessive brittleness. The blade seamlessly integrates with a classic d-shaped magnolia handle adorned by a black horn ferrule.

The kamagata usuba is a traditional Japanese vegetable knife characterized by its unique curved profile and pointed tip. Ideal for precise vegetable cuts and decorative work, it provides versatility in the kitchen while excelling in delicate slicing and intricate garnishing.

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.
