Nontron knives are produced in the village of Nontron by Coutellerie Nontronnaise. They feature a turning ferrule that dates back to the 1600's that holds the blade in a locked position. The Boxwood models feature patterns burned into the wood that make little 'flies,' although no one is quite sure what they represent.
