Round molding plane comprised of three parts, a wooden rectangular body with an angled cutout through the middle and a round profile (a), a wooden wedge that tapers to a point at the bottom and has a rounded top (b), and an iron with a curved blade to match the round profile on the body (c). The wedge and the iron fit together inside of the plane's cutout, and the wedge holds the iron in place as it cuts the wood below. Stamped on the toe of the plane is "I BLOWER", "I UTTER", and "WALLACE MONTREAL". Stamped on the heel is "I BLOWER", and the number "18". Stamped on the iron is "THOs FIRTH & SONS".
Round planes are one of the basic molding tools. They cut convex circular grooves into a workpiece. They are found paired with hollow planes of the corresponding shape. They can be used for shaping, trimming and molding. They can be used in conjunction with other planes to create any shape imaginable. Sets of hollow and round planes are an essential part of a woodworker’s toolkit.
