Another job you probably wouldn't want to do, Knife maker

Craftsmen in the French knifemaking city of Thiers lie on wooden planks over the large water-driven and lubricated grindstones to grind knives to shape. The prone position allowed them to apply more pressure on the blade, the board also protects them from the spray of water. Looks exhausting. Not only tiring, but cold and damp also, so these workers have trained their dogs to lie on their legs to keep them warm.
