Precision wing divider scriber made from high-quality carbon steel for durable, accurate marking and measuring. Key benefits Accurate, repeatable marks: precision-polished clamping feet, a heat-treated head and a screw-locking arm let you set and hold a fixed radius for consistent arcs and circles. Durable construction: high-quality carbon steel and careful heat treatment maintain rigidity and long-term performance under normal shop use. Easy pencil/pen changes: integrated pen case/holder and fixed wings let you swap or sharpen the pencil quickly (pencil not included), so you spend less time resetting tools and more time working. Fine control for precise layout: a fine-adjustment nut plus spring tension stabilizes the arm and provides smooth, controlled tightening for exact measurements. Versatile marking tool: combines the functions of a wing divider and scriber to measure, scribe, and mark on wood, metal, leather and other materials. Features Material: high-quality carbon steel body with precision-polished clamping feet. Head treatment: heat-treated head for improved strength and wear resistance. Wing divider function: adjustable winged handle and fixed arm with locking screw for reliable radius control. Pen holder/pen case: built-in holder accepts a pencil or scribing implement (pencil not included) for convenient replacement and sharpening. Fine adjustment and spring tension: fine adjustment nut for small radius changes and spring tension to stabilize control during marking. Compatibility and usage notes Designed to accept common pencils or scribing implements; pencil not included. Locking screw and fixed arm allow repeatable measurements across multiple workpieces. Suitable for layout, scribing, and circle/arc transfer tasks where repeatable, precise control is required. Typical applications Woodworking: marking precise circles and arcs for joinery, cut lines and template work. Metalworking and fabrication: transferring dimensions, scribing centerlines or marking drill points on sheet metal and plate. Crafts and leatherwork: laying out patterns, cutting lines and detailed shape marking where consistent radii are needed. What makes it stand out Combines robust carbon-steel construction and heat-treated components with a user-friendly pen holder and fine adjustment mechanism to deliver repeatable precision and quick setup. Built for tradespeople and hobbyists who need a dependable, easy-to-adjust divider that holds settings and simplifies pencil changes. Note: pencil is not included.
