Pablo Picasso was known for many things: He was an artistic pioneer; a fierce opponent of authoritarianism; and a lover of Opinel knives. Because he spent most of his life in France, it’s little wonder that Picasso stumbled upon these pocket-sized marvels. He was particularly fond of the No. 05, which was perfect for performing small everyday tasks, as well as sculpting figurines. For Picasso, the No. 05 was a perfect combination of functional tool and artistic expression.
