Use the Robert Sorby Box Cutter to create parallel sides on boxes and vases. The Robert Sorby Box Cutter is equally adept at creating flat bottomed surfaces and delivering those perfectly crisp corners on small projects. This cutter is compatible with these tools: Box Hollower (803H) Mushroom Tool (804H) Captive Ring Tool (805H) Sharpening: Use a diamond file or honing stone flat across the top face. Keep the surface sharp for best results, sharpen frequently. Sharpening can be achieved with the cutter mounted on the tool. Alternatively use the 472 cutter holder to reshape the profile on the Robert Sorby ProEdge or on a grinding wheel.
