The British No.9 Mk I socket bayonet was the result of a post-war desire to replace the unpopular No.4 spike bayonet. 

Production commenced in 1947 and between 1947 and 1949, around 200,000 No.9 Mk I bayonets were produced at the Royal Ordinance Factory at Poole in Dorset. 

In 1949, production of the No.9 bayonet moved to the Royal Small Arms Factory (RSAF) factory at Enfield. 

RSAF produced 366.902 No.9 bayonets between 1949 and 1956, with a final batch of 10,000 being made in 1962.
