This Yoita Soichiro Mini Concave Hollow Plane 18mm is a specialised Japanese kanna designed to carve and refine convex wood surfaces with exceptional control. Its gently curved sole allows for smooth contact with curved wood contours, while the sharp SK-5 carbon steel blade delivers accurate, clean cuts with minimal resistance. The tool’s oak body offers a natural, comfortable grip, making it easy to use even during extended work sessions.
This tool is ideal for shaping inner curves on furniture components, hollow forms, instrument soundboards, or intricate joinery. It is particularly suited for woodworkers, luthiers, and hobbyists who need precision when working inside curves or channels. It can also be used creatively in sculptural woodwork where convex shaping is needed.
