The finest restaurants serve steaks with original Laguiole knives. The slender blade and elegant lines have made the knives world-famous. The Laguiole is a traditional French pocket knife named after a region in the south of France. There, the knife was designed by Pierre-Jean Calmels in the 19th century. The signature bee or fly on the spine serves as a trademark that differs from one knifemaker to the next.
