Wooden round molding plane consisting of three parts.
a- The body is made of a brown hardwood and is rectangular in shape. A cheek protrudes from the lower half of both the front and back sides. The top proper-left corner is rounded. All top edges are chamfered. The sole is curved concavely to match the cutting edge of the iron. The throat is centred and runs diagonally through the body. Stamps on toe read: " T. ST JOHN" (X2); "I BLOWER"; "B"; One mark scratched out. Stamps on heel read:"I BLOWER"; "(C. ST JOHN)?". Inscriptions on back read: "(BEWOGY-R)?"; "LEEDS".
b- The wedge is made of the same hardwood as the body. It tapers to a point on one end and is rounded on the other. A trapezoidal cut-out allows for easy handling.
c- The iron is a thin long piece of dark grey metal. It abruptly widens near the cutting edge, 5cm from the bottom. The cutting edge is rounded concavely to produce convex bead cuts. The cutting edge is worn and the corners are rounded.


Round planes are one of the basic molding tools. They cut convex 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.
