A tool is disclosed for selective honing of the outer diameter of a cylinder using an abrasive belt in semi-circular contact upon the outer-diameter of a cylindrical work-piece to perform a similar function to honing the inner-diameter of a hollow cylinder. The belt is retained within the tool body by U-shaped restraint arms, and a slot in the tool body. A clamp block retains the ends of the belt which exit the slot. Springs on the arms, and contact of the block on the outside of the tool body, force the belt into a triangular shape inside the body. A cylindrical work-piece inserted within the triangular shaped belt causes the belt to deform into three semi-circular areas of contact between the belt and work-piece. When the work-piece is rotated, the belt abrades material from the work-piece.
