This Sukenari 240mm gyuto knife, made of HAP40 steel, one of the hardest alloys used to make kitchen knives, have a nice minimalist aesthetics and equally excellent performance. The intrinsic toughness of this powdered steel allows for far thinner grinding than is possible with other steels. Furthermore, it maintains that sharpness is far longer than most others. If you're looking for a Japanese knife with amazing edge retention, the Sukenari HAP40 series should be at the top of your list.

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.
