Second Taiwan Strait Crisis
During the Second Taiwan Strait Crisis, the People's Liberation Army (PLA) of the People's Republic of China fired around 1,000,000 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 10 to 60 cleavers from one artillery shell and tourists often purchase Kinmen knives as souvenirs together with other local specialties.
