The best use of guns that I ever seen: Transforming Weapons – Peace Art Cambodia.
In 1998, the Royal Government of Cambodia began tackling the proliferation of illegal and surplus small arms through an integrated programme. By 2006, over 160,000 small arms had been publicly destroyed in Flame of Peace ceremonies.
In October 2003, Peace Art Cambodia began a metalwork skills training programme for apprentice artisans using thousands of these weapons as raw material.
