Opinel knife

The Opinel company has manufactured and marketed a line of eponymous wooden-handled knives since 1890 from its headquarters in Saint-Jean-de-Maurienne, Savoie, France—where the family-run company also operates a museum dedicated to its knives. The company sells approximately 15 million knives annually. Opinel knives are made of both high carbon and stainless steel, the latter being the highest quality Sandvik steel from Sweden.

Originally sold as a working man's knife, an Opinel knife has become emblematic of French culture, with Pablo Picasso reportedly using one of the company's knives as a sculpting tool. In 1989, the Larousse dictionary cited "Opinel" as a registered trademark—and in the French language, the term "Opinel" has become a genericized trademark to refer to any wood handled folding knife, not necessarily only those made by the company.

Joseph Opinel began making knives in 1890 in Savoie, France as a simple working man's or peasant's knife. It proved popular with the local farmers, herdsmen, and paysans-vignerons (peasant winemakers) of the area. In 1897, a series of twelve sizes, numbered 1 to 12, was developed. From 1901–1903, Joseph Opinel built his first factory in Pont de Gévoudaz and produced a machine for mass production of the knife's wooden handles.

The company hired peddlers to sell the knives and opened a small shop near the Chambéry railway junction, where the knives became popular with PLM railroad workers, who in turn spread word of the brand throughout France. By 1909, Opinel had registered his first trademark for the Opinel knife, choosing the main couronnée ('crowned hand") as his emblem. A few years later Opinel annual sales were in the hundreds of thousands, and by the start of World War II as many as 20 million knives had been sold.

The Opinel Virobloc or safety twistlock mechanism was invented by Marcel Opinel in 1955, increasing the safety and versatility of the knife by allowing the blade to be locked in the open position. In 2000, the Virobloc locking mechanism was improved to allow locking the blade in either the open or closed position.
