This Umebachi Ryuma 18mm Hollow Forkstaff Plane is ideal for making convex edge shaping, and round profile on the sides of woodwork. The curved blade and compact body give users clean and accurate control over interior contours and sculpted cuts in tight areas.

It is well-suited for tasks such as shaping convex decorative profiles in cabinetry, joinery, and sculptures. Its round design allows it to reach areas inaccessible to flat planes, making it a staple for woodworkers handling curved forms.

Product Data:
• Blade Width: 18mm
• Weight: 170g
• Blade Shape: Curved (Round)
• Handle Material: Hardwood
• Country of Origin: Japan

To use, brace the plane with a firm grip and guide it along the concave area to be shaped. Keep steady pressure and let the curved blade engage the material gradually, adjusting angle and force to suit the wood’s grain and hardness.

Wipe clean and oil the blade after each use to prevent rust. Store in a dry area and ensure the cutting edge does not come into contact with hard surfaces. Wear gloves when handling and keep away from children.
