Kiyoshi Kato-san, (or Yoshiaki Fujiwara--his smith name) born in 1944, is a licensed swordsmith (since 1999). He was 20 years old when he began his swordsmith training under his grandfather, Kanekuni Kato, and his father, Sanehira Kato.

After more than a decade of training and swordsmithing, he entered the field of knife-making (outdoor and kitchen knives) in 1977. He makes his knives in his workshop in Hokuto City in Yamanashi prefecture.

Kato-san's knives are one of the most highly sought-after pieces among Japanese knife collectors. His knives, as you might have guessed, are also considered as "unicorns" just like Shigefusa knives.

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.
