HOCK Scratch Stocks are made from tough, wear-resistant bamboo plywood. We've included two spring steel blades, one of which has a quirk-bead shape cut into it, to get you started using your Scratch Stock with no more than final honing. Other shapes are up to your imagination and are cut into the blades with files and slipstones. The body measures 3/4" x 1-1/2" x 4-3/4", the blue-tempered spring steel blades are .050" by 3/4 x 1-3/4"
