Thiers-country knifemaking emerged seven centuries ago, in the Durolle valley, when the early knifemakers harnessed the hydraulic power of the Durolle river to drive ‘rouets’, a sort of grindstone millwheel used specifically to grind down and sharpen knife blades. Today, the Vallée des Rouets—which harbours the very last working ‘rouet’ grinding mill—welcomes visitors for a peek into this industrial-heritage past The Musée de la Coutellerie rounds off the experience by showcasing a vast collection of locally-made knives and retracing how the art of knifesmithing evolved over the centuries.
