NONTRON is the founder of the knife in France. The Nontronnaise Cutlery existed since 1653 and has centuries of experience. This switchblade knife is a reproduction of an old model of the 1914-1918 war. Boxwood handle pyrographed 11cm. 9cm stainless steel blade. Simple but rather special closure. Just pull on the ring with the index finger and push the blade with the thumb. The various safety catches on the handle then guide you.
