Kinmen knife

The Kinmen knife () is a Chinese-style cooking knife exclusively made in Kinmen County in Fujian Province, Republic of China. The knives were once made from the remains of artillery shells fired by the United States and Allied forces in World War II, when the island was occupied by the Empire of Japan, and by mainland China between 1958 and 1978.
During the Second Taiwan Strait Crisis, the People's Liberation Army (PLA) of the People's Republic of China fired around 450,000 shells at the Kinmen islands in its conflict against the Republic of China which controls the islands. The shells have become a resource of steel for the local economy. Since the Second Taiwan Strait Crisis, Kinmen has become famous for its production of cleavers made from PRC artillery shells. Many of the shells in the later stages of the war were propaganda shells, with the high-explosive removed and replaced with stuffed leaflets, thus impacting on the island intact, rather than exploding into many tiny fragments. A blacksmith in Kinmen generally produces 60 cleavers from one artillery shell and tourists often purchase Kinmen knives as souvenirs together with other local specialties.
During his visit to Kinmen on 23–24 May 2015, Zhang Zhijun, head of the Taiwan Affairs Office of Mainland China, received a Kinmen knife as a gift made from PLA shells. This was a gesture symbolizing the two sides of the Taiwan Strait have buried the hatchet left from Chinese Civil War and are working towards mutual peace.
