The Conical Shredder – indispensable for longer strokes, good for texturing and working on rounded surfaces. The Mudtools Shredder is an indispensable tool for shaping and carving leather hard clay. For years you could find a tool like this at the hardware store. This rasp was designed to be used on wood. Clay people, sculptors and car-body repairmen discovered how well the blade worked on other materials (like clay andcar body filler). The problem was the handle design. The handle would trap clay and get clogged up. Michael designed a new open blade shape as well as a comfortable ergonomic grip. It functions well, doesn’t trap the waste clay in the tool and doesn’t frustrate the user. An added benefit is the tool mark, it leaves a handsome textured surface in the clay.
