SUMU is one of cutlery series made of zirconia. They do not interfere with the flavours of dishes as absolutely no metallic ions are released. Consequently, they never become the cause of metallic allergies. You can focus on your sense of taste as the thin, silky finish of the zirconia tip makes it easy to take hold of the food with exceptionally smooth feeling in and out of the mouth. The matte zirconia cutleries softly reflecting atmospheric lighting shall bring serenity to the dining scene.

I am working with the team to develop the Zirconia products since 2007. I started my career with Injection molding technology. I mainly have been occupying for technical development. Through this experiment, I have understanding about chemicals. I am interested in new chemical materials.

OJI&DESIGN is the design company and ZIKICO INC is the client. This nominate is done by ZIKICO INC. ZIKICO is a product brand specialized in a material called "Zirconia" which has three characteristics. Zirconia is derived from minerals; its hardness is next to diamond and ruby. Zirconia is composed of two different kinds of crystals. One features durability, and the other flexibility like metals. It pliantly changes its shape by external forces. Zirconia is ceramics sintered at a high temperature of approximately 1,400 ° C. Being similar to bone china, there is no dissolution of metal ions at all. Consequently, it does not cause any allergy. As hard as a jewel. As flexible as metals. Non-allergic like bone china. To put it in a word, zirconia, is “Purity.” ZIKICO shall contribute to the society by producing products based on “pure” zirconia.
