Seki is the Solingen of Japan. Thanks to its perfect abundance of resources such as ore, wood, and water, Seki developed into a stronghold of swordsmithing more than 1,000 years ago. Sumikama Cutlery, the inventor of the Damascus knife and manufacturer of Kasumi knives , is headquartered here. This traditional company boasts many years of experience in traditional blacksmithing, working with high-quality materials, and continuous and innovative development.

The Masterpiece knife series represents an exceptional quality product. Through repeated folding and forging of VG10 cobalt steel, KASUMI knives acquire their wave-like Damascus pattern. After the production process, the blades are polished to a high gloss by highly experienced grinders, which further enhances the distinctive pattern. The handle is made of linen resin, a highly durable, dimensionally stable, and moisture-resistant material. This ensures that the knives meet even the highest demands of professionals.
