Precise layout and marking: Steel flat legs with hardened points give stable contact and accurate markings for circles, arcs, and edge scribing. The tool locks at the set distance so your measurements stay consistent while you work. Fast penbased circles: A builtin pen holder quickly grips a pen for drawing circles without switching tools. Use the same device for scribing with the point or sketching with ink. Secure on flat materials: The divider can be fixed and used on horizontal surfaces such as leather and wood, making it easy to lock and repeat a radius across the workpiece. Reliable construction: The spring wing divider caliper uses a spring tension and locking nut to hold settings firmly. Quality materials and construction deliver repeatable performance for marking and layout tasks. Fine, quick adjustment: Adjust distance between the legs with the spring tension and adjustable nut for fast, precise changes. Supports a maximum radius of 103 mm for a wide range of circle sizes. Versatile tasks: Designed for drawing arcs and circles, creating protractors and dividing lines, marking contours, and scoring edges—suitable for detailed layout and design work in multiple materials. Typical applications Leatherwork: Mark stitch lines, cutting arcs, and edge profiles on hides and straps while keeping repeatable distances for multiple pieces. Woodworking: Lay out joinery, mark circular guide lines and contours, and transfer consistent measurements across boards and panels. Metalworking and small fabrication: Scribe arcs and reference lines for drilling, cutting, or bending operations that require accurate, repeatable radii.
