An Opinel knife, or simply Opinel, is a folding knife with a wooden handle that has been manufactured by the company of the same name in the French Savoy region since the late 19th century.
The knife, originally designed for agricultural work, has undergone only minor changes in function and design over the years as it was further developed.
It is internationally renowned and widely distributed in the millions. In its country of origin, France, in particular, the Opinel is considered a classic of everyday culture.
