About Us

The World’s Cutting Technology Organisation

CATRA is the world’s leading authority on the testing of cutlery and knives for manufacturers, retailers and consumers, having made significant contributions to the development of the ISO Standards for manufacturing and testing of those items.

From our research in knife edge design and manufacturing techniques, we have developed a range of sharpeners for commercial and domestic markets, which are quick and easy to use and produce blade edges that are sharper and more durable than the day of purchase! These products are all available for purchase on this website and can be shipped anywhere in the world.

All CATRA products sold on this site are designed and built in Sheffield UK by CATRA or our associate companies.
