Kyocera's story began in 1959 in Kyoto, Japan, with a focus on advanced ceramics. For over 60 years, they've pioneered ceramic technology, from semiconductors to medical implants. The DS20S sharpener was born from a simple problem: modern life dulls even the best blades. We designed it for people who value precision but don't have time for complicated tools. Every component is engineered in Japan, using the same high-purity alumina ceramic found in their industrial products. It's not just a sharpener; it's a compact piece of Japanese engineering designed to restore your tools to their intended potential. This model is consistently a top-rated sharpener in its category for its reliability and simplicity.

The Kyocera DS20S Diamond Knife Sharpener is a compact ceramic stone sharpener that utilizes a diamond-coated ceramic base as its primary ingredient. The diamond particles are embedded into the ceramic surface, providing an exceptionally hard and abrasive material designed to efficiently sharpen dull blades by removing small amounts of metal to restore a precise edge. Ceramic, known for its durability and resistance to wear, serves as the stable foundation that ensures consistent sharpening performance over time. This combination allows the sharpener to effectively hone a variety of blade types, including those made from stainless steel or high-carbon steel, offering users a quick and reliable method to maintain sharpness. The benefits include prolonged knife lifespan, enhanced cutting precision, and reduced effort in kitchen tasks, all within a portable design ideal for home or professional use.
