📜 The Story Behind This Knife
In mid-to-late 20th-century Japan, regional Agricultural Cooperatives (Nōkyō) frequently merged to pool resources and consolidate local farming districts. To celebrate these historic mergers, the cooperative management would commission bulk runs of traditional, high-quality forged kitchen cutlery from reputable cutlery hubs like Sakai.
These knives were handed out as exclusive, premium commemorative gifts to local member farmers, cooperative employees, or community leaders.
💡 Knife Type: Usuba / Nakiri
This blade geometry is a traditional Nakiri or Usuba Hōchō, instantly recognizable by its flat, rectangular profile and squared-off nose. It is specifically designed as a dedicated vegetable knife, allowing you to make clean, flush contact across the entire cutting board to smoothly chop, slice, and push-cut greens without creating "accordion" veggies.
