If you want to turn bowls, platters, furniture components and other larger scale work, Ultra- Shear Full-Size Tools are perfect for you. All the joys of turning without the complicated learning curve involved in traditional tools or the expensive and complicated sharpening equipment, either. The cutting edge is an industry-leading nano-grain carbide insert that rivals high speed steel for edge quality, but outperforms high speed steel for edge retention by 20 to 30 times. When you do need a fresh edge, just loosen the retention screw, turn the cutter, lock it back up and get back to work.
