This is the outcome of collaboration between Final Aim, a design specialist, and Web3 blockchain based in the US and Japan, along with Studio Shikumi and the 15th-century artisan Kawachinokami Kunisuke. This sword was not designed by humans, but instead by artificial intelligence, borrowing from Japan's traditional katana forging techniques to turn the blueprint into a product.Speaking specifically about the artisan, there is a tradition where a master artisan, upon retirement, passes on the prestigious title to the most talented disciple. The first Kawachinokami Kunisuke forged katanas about 400 years ago, and the 2022 Kawachinokami Kunisuke, whose real name is Kunihara Kawachi, continues to draw on all the experience and knowledge accumulated over four centuries to create katanas following the most traditional crafting process.
Of course, this doesn't make Mr. Kawachi obsolete, it just leads to creations with a traditional flair. Evidence lies in how AI's design has been brought to life by him; the sword's handle resembles a weapon straight out of Resident Evil:



This one is called Tachi (タチ), designed to maximize the durability and strength of the blade while ensuring maximum comfort in wielding the sword handle, yet minimizing the amount of material needed to forge this katana.Tachi was recently exhibited in New Orleans, USA, and is scheduled to be showcased in Japan and various other regions. Studio Shikumi will handle orders and sales of this limited quantity item, although the selling price remains uncertain.According to Live Japan
