George IV expressed his enthusiasm for weapons and military dress in his large collections at Carlton House. By 1819 his Armoury had expanded to fill several apartments. Contemporaries recorded the extensive and varied nature of the collection, which comprised both historic British and European arms, armour and uniforms, and an equally impressive collection from beyond Europe. The range of sources was extensive and included a number of works from Malaya and Java, including this kris, which was presented by Stamford Raffles on 17 July 1813.

The kris and sheath likely originated from Central Java. The blade is made from pattern-welded iron and steel, probably with a high nickel content. It has a distinctive serrated edge on one side. The hilt and scabbard are decorated with gold, red gold and diamonds.
