Kyocera sold its first ceramic knife in 1984 and recently received its 34th patent for ceramic knife technology.

Kyocera Corporation (“Kyocera”) today announced its 34th patent for its proprietary ceramic knife technology, cementing its position as the industry leader in ceramic kitchen knives. A Kyocera patent from back in the 1980s covered a method for grinding ceramic tool blades, which became the driving force for mass production. Today, INNOVATIONblack®, Kyocera’s latest patented ceramic knife, has been shown to stay razor-sharp twice as long as traditional ceramic knives. *INNOVATIONblack® pioneered the fusion of new ceramic materials and represents over 12 years of dedicated research and development (R&D) to master the proper composition and sintering of ceramic particles for superior performance and durability. https://cutlery.kyocera.com/
Kyocera Upholds 1,600-Year Tradition with Patented New Materials and Technologies
The sword is said to have been introduced to Japan in the fourth century. In 794, Kyoto became the capital of Japan, where culture, arts and crafts flourished – local resources such as iron, whetstones, charcoal and water made the area a natural place to make knives. Kyoto soon flourished as a blacksmith town and became famous in Japan as a great source of tableware.
Fast forward to 1959: Kyocera was founded in Kyoto as a pioneer in the field of advanced ceramics (Kyocera = “Kyoto” + “ceramic”). Today, Kyocera is the world’s leading manufacturer of innovative fine ceramic products and components used in everything from mobile devices and space vehicles to artificial hip joints and, of course, ceramic tableware and kitchen tools.
Inspired by the Kyoto DNA nurtured by Kyoto culture and technology, Kyocera focuses on the superior material properties of engineered ceramics, such as extreme hardness, weight and corrosion resistance. The company began researching and developing ceramic knives in the early 1980s. After much trial and error, including learning traditional blade sharpening techniques in Gifu, another famous tableware center in Japan, Kyocera produced and sold its first ceramic knife in 1984. Subsequently, Kyocera became one of the first companies in the world to successfully mass-produce zirconia ceramic knives.
KYOCERA was named a 2022 “Top 100 Global Innovator” by Philadelphia-based ClarivateTM, a global leader in delivering trusted insights and analytics to accelerate the pace of innovation.
As a pioneer in ceramic tableware, Kyocera has been awarded 34 patents and utility models worldwide related to the reliability, uniqueness, technical prowess and quality of knives. These intellectual property (IP) registrations have been obtained from authorities in Japan, the United States, Europe and China. Today, Kyocera is the leading creator of ceramic knives and kitchen tools for the household goods industry.
For example, JP 3905062, filed in Japan in 2003, discloses a unique circular geometry at the tip of the blade that improves durability. Over the years, Kyocera ceramic knives have been identified by their unique rounded tip design. Kyocera combines two different hardness levels of ceramic materials, protected by JP 6151878 (submitted in Japan in 2015), to create a blade that remains 2 times sharper than conventional ceramic blades while maintaining chip resistance. This ensures the high quality of Kyocera’s current top-of-the-line cutlery INNOVATIONblack® range. Today, the invention of JP 6151878 has been patented in Japan, Europe, China and the US, including US 10118302 B2.
Not only does Kyocera have a long history and tradition in the manufacture of ceramic knives, but the company is constantly developing new technologies to improve performance and user experience (eg pending PCT applications – WO2021187327 A1, WO2022210604 A1). In addition to patents and utility models, Kyocera has accumulated its own manufacturing know-how through in-house production of knives, continuing to offer high-quality ceramic knives made in Japan at affordable prices.

The Kyocera Group (TOKYO:6971, https://global.kyocera.com/), the parent company and global headquarters of the Kyocera Group, was established in 1959 as a producer of fine ceramics (also known as “premium ceramics”). By combining these engineered materials with metals and combining them with other technologies, Kyocera has become a leading supplier of industrial and automotive components, semiconductor packaging, electronic devices, smart energy systems, printers, copiers and mobile phones. For the year ended March 31, 2022, the company’s consolidated sales revenue totaled 1.8 trillion yen ($15.1 billion). Kyocera is ranked 665th on Forbes Magazine’s 2022 “Global 2000” list of the world’s largest public companies, and has been named “World’s 100 Most Sustainably Managed Companies” by The Wall Street Journal.
