The origins of the Kujira Knife trace back to a heartwarming tale. It all began when a request was made for a knife without a sharp point that could be safely used by schoolchildren to sharpen pencils. This simple yet practical need sparked the creative ingenuity of the Tosa blacksmiths.

As the craftsmen began to fashion a prototype knife, an unexpected resemblance to a whale, one of the symbols of Kochi, emerged. This happy coincidence marked the birth of the first whale-shaped knife, capturing the essence of both functionality and local identity.

Since then, the Kujira Knife has gained popularity both at home and abroad, as its unique design and exceptional versatility captivate enthusiasts and collectors alike. The blades, artfully shaped to resemble the majestic baleen mouths of whales, embody the meticulous artistry and attention to detail that define the Tosa blacksmith tradition.
