The Craft Sha Leathercraft Round Shape Modeling Tool is designed for shaping and refining leather surfaces during leather carving and embossing work. The tool features a 15mm round modeling tip that allows controlled pressure when forming patterns, smoothing carved areas, and shaping leather fibers.The rounded modeling surface allows the tool to glide across cased leather without cutting the material. In leathercraft, slightly dampening the leather before tooling is known as “casing,” which softens the fibers and allows them to be compressed and shaped more effectively. This makes the tool useful for refining swivel knife cuts, smoothing background areas, and compressing leather fibers to enhance the definition of carved patterns.For increased effectiveness, the metal modeling tip may be gently warmed using an alcohol burner. Mild heat allows the tool to glide more smoothly across the leather surface and helps compress fibers more efficiently during detailed modeling work.This modeling tool is best paired with the Craft Sha Leathercraft Spoon Shape Modeling Tool and the Craft Sha Leathercraft Tooling Sponge Foam Board, which together provide the proper support and control needed when shaping and compressing leather fibers during detailed leathercraft work.Product Data:• Brand: Craft Sha• Product Type: Leathercraft Modeling Tool• Tip Shape: Round Shape• Tip Size: 15mm• Handle material: Wood• Application: Leather embossing, shaping, and detailing• Handle: Wooden handle with metal modeling tipTo use the tool, case the leather by lightly dampening the surface before applying controlled pressure with the round modeling tip. Move the tool across the leather to compress and shape the fibers, refining carved lines and smoothing decorative surfaces. The rounded tip allows shaping without cutting the leather. If desired, the metal tip may be mildly heated using an alcohol burner to improve glide and shaping performance.Please note that this listing includes the Round Shape Modeling Tool only.
