History.
CATRA was originally set up by the British Government in 1952 to carry out developments for the UK's cutlery and knife industries, for which the area of Sheffield in Yorkshire is world-famous.
CATRA has developed a range of unique machines for measuring the cutting performance of all types of cutting edges from razor blades to large knives used in machinery and for testing of blade performance in general.
Since the 1980s CATRA has become an internationally recognised (60% export, CATRA published accounts 2013) cutting technology organisation, supplying consultancy, testing services and knife/blade making and testing equipment to manufacturers, developers, designers, users and retailers. Their particular expertise is unusual and important to the knife history and culture of Sheffield.
Aims.
CATRA's aim is to provide manufacturers, retailers and users of all types of cutting implements with independent technical experts that can advise, carry out product comparisons/tests and develop blade, knife and cutting technologies.
