In 1930, Cooper’s was incorporated with £6,000 capital at Lockfast Works, Hermitage Street, by Harold Laycock Cooper (1890-1947) and Ralph Cooper (1895-1965).  They were the sons of John Isaac Cooper, a cycle maker, and his wife, Mary Hannah.  Harold initially worked in a saw warehouse.  The firm specialised in tools, but in the 1930s also marketed stainless cutlery.  At the British Industries Fair (1937), Cooper’s exhibited ‘safety razor blades that fit most three peg holders’.  These were marked ‘FULUSE’, which was also the name of the factory during the 1930s. Fuluse Works had discontinued safety razor blades and henceforth concentrated on tools (and knives) for the engineer, builder, and gardener.  ‘SIGNAL’ was another Cooper trade name.  In 1968, Cooper’s was acquired by Archford Investments (also owners of Joseph Rodgers & Sons) and Fuluse Works moved to St Mary’s Gate.
