Additional Information: This plane is a specialized Japanese woodworking hand plane designed to dimension multiple thin wooden strips—such as kumiko lattice pieces for shoji screens and lattice doors—to the exact same uniform thickness all at once. It originates from a retired miyadaiku (traditional temple carpenter) in the Tokyo area, being one of several planes he purchased in his youth and has carefully preserved ever since. The plane has been exceptionally well preserved by this miyadaiku carpenter; the blade shows only a single spot of light surface rust, and the dai (wooden body) exhibits no noticeable warping or twisting. However, if you intend to put it to work, you will need to spend some time conditioning the sole and sharpening the blade to your preferences.
