This Umebachi Ryoma 18mm Carving Round Plane is designed for detailed wood shaping, enabling smooth scooping and hollowing along curved surfaces. Its compact body, tightly seated blade, and round-bottom profile offer confident handling and effective material removal with minimal tear-out.

It is particularly useful for concave shaping, curved joinery, bowl work, masks, and relief carving. Carpenters and woodworkers value this tool for cleaning up recesses, smoothing routed profiles, or adjusting curved joints. It is also suited to shaping decorative elements or refining traditional Japanese woodworking details.

Product Data:
• Blade Width: 18mm
• Body Length: Approx. 185mm
• Blade Material: Carbon tool steel
• Handle Material: Natural hardwood

Hold the plane securely and draw it along the wood surface, keeping the flat sole in contact while allowing the curved cutting edge to follow the arc of the workpiece. Use short, controlled passes and refine pressure based on depth of cut. Always adjust the blade depth prior to use.

Keep the blade clean and lightly oiled after each use to prevent corrosion. Store in a dry location with the cutting edge protected. Do not plane nails, metal, or other hard inclusions.
