Umebachi Ryuma 24mm Wood Kanna Convex Compass Plane Curved Sole Round Bottom

This Umebachi Ryuma Compass Plane is designed for precise planing on curved wood surfaces where standard flat planes cannot reach. Its curved sole provides the control needed to refine contours, offering woodworkers a reliable way to handle complex shapes with confidence, and the round bottom ensures better conforming to hollow chapes, such as bowls or spoons.The tool is especially effective for shaping softwood, adjusting surface levels on contoured timber, and fine-tuning the final curvature of wood elements in furniture-making or general carpentry. Its size and blade width allow for targeted work on irregular or rounded surfaces where flat-bottomed planes would chatter or skip.Product Data:• Approximate Dimensions: Width 22 x Height 32 x Depth 142mm• Blade Width: 24mm• Handle Material: Natural wood• Blade Material: Forged carbon tool steelTo use the plane, hold the body firmly with both hands and draw it toward you in smooth, controlled passes along the curved wood surface. Light pressure and gradual removal are key to avoiding tear-out. Blade projection can be adjusted by tapping lightly on the blade or body using traditional kanna setting techniques.Keep the blade lightly oiled after each use to prevent rust, and store the plane in a dry area away from humidity. Periodically check the blade for sharpness and hone as needed. As the blade is made from carbon tool steel, avoid prolonged contact with moisture. Keep out of reach of children and use with appropriate caution.
