Toothed on the external face and smooth on the inside, Iwasaki half round files are lovely precise tools for shaping internal curves.
The teeth of this file are chemically etched to produce accurate, consistent sharpness and even height. Designed specifically for wood, they cut fast with almost no pressure, don’t clog, and leave an exceptionally fine surface.
Japanese carving files are designed to work with the grain. The tool will work efficiently under its own weight, reducing the pressure as you approach the finished shape will help to yield the smoothest possible finish.
