About IOXIO®

IOXIO was founded by Udo Rieser under the name High Tech Ceramic e.K. as a German manufacturer of ceramic and plastic household items. All our products are developed in Wiesbaden and manufactured from high-quality European raw materials. Our own production is now based in the Czech Republic. Our products are developed and manufactured for quality and durability.

Our products are developed and manufactured with the aim of longevity, quality, pleasure and ease in the kitchen and personal hygiene.

Udo Rieser started out in the knife and scissors sector with “Rieser Messer” and steelware from Solingen. Over time, the steelware became harder and harder and conventional knife sharpeners were no longer durable enough. Faced with this problem, he developed the first ceramic sharpening rods in the early 1980s with the aim of creating knife sharpeners that were “harder than steel”. Oxide ceramics, harder than steel and a natural product, became the ideal material. Even back then, the focus was on sustainability and durability.

Udo Rieser developed the world's first ceramic knife sharpeners, nail files and foot rasps. His breakthrough came in 1988 at the Inventors' Fair in Geneva, where he was awarded the gold medal for a ceramic knife sharpener.
The original Rieser ceramic sharpening roller revolutionized knife sharpening.
Since then, Udo Rieser and his team have been producing durable sharpening systems and care products for the private label sector.
This success has led to numerous patents and registered designs in the sharpening systems, foot care and nail care categories.

IOXIO is a family-run company in its second generation. Nadine Rieser took over High Tech Ceramic e.K. from her father Udo Rieser in 2020. She was given a passion for high-quality products at an early age. Having worked for the company for 21 years, she combines her passion with the goal of making customers happy. Together with the creative IOXIO team, they develop innovative products of the highest quality and durability that make life easier.
