This is Tony Del Ciello, from the Italian town of that  name, who lives mostly in Chicago these days and blesses us with a little chunk of life the way it could be.  Once a year he pedals this wagon through my neighborhood, ringing his bells, and people come out of their houses with armloads of knives, which he sharpens by hand on this stone wheel.  Dirt cheap, may I add.  I must have had twenty knives sharpened by him today.
