This set contains four carving blades, a quick-connect ABS handle, an 11-pocket tool roll, a custom strop and polishing compound. It includes one #6 x 5/16 Sweep, #11 x 1/8" Sweep, one 1mm x 45 degree V-Tool and one 1/4" x 70 degree V-Tool. This set is ideal for relief printing, which is based on a reductive process; carve the non-image away from a flat, level surface and ink the remaining top surface with a roller or brayer in order to print the image.
