  In 1590, warlord Chosokabe Motochika unified Tosa, documenting 399 blacksmiths in the region. Known for its forest-rich environment, Tosa required durable, high-performance tools for forestry, leading to the establishment of specialized blacksmiths. Following this tradition, Kajihira Tomika founded the Ishizuchi Agricultural Tool Company in 1920. Over 100 years later, they continue to maintain the distinctive thick, reassuring spine of Tosa knives while achieving the sharpness expected of fine Japanese knives.
