High-quality carbon steel construction Made from durable, high-quality carbon steel for strength and toughness. Smooth, rust-resistant finish for long-term use and a professional appearance. High hardness resists wear so the tool keeps its shape under repeated use. Precision hardened points and reliable fittings Hardened steel points and solid pivot fittings provide accurate, repeatable scribing and measuring. Robust springs and pivot points maintain consistent tension so marks stay true across jobs. Controlled adjustment and secure locking Centre-mounted spring and torque (speed) nut deliver smooth, balanced control during use. Adjustable speed nut lets you fine-tune tension and movement for precise spacing. Lockable distance ensures you can fix a setting and reproduce the same contour or circle reliably. Easy to use on leather, wood and similar materials Top-mounted tip holds steady against the work surface to prevent slipping. Set and lock the required span, then scribe clean contours, circles or transfer measurements with confidence. Practical applications Woodworking: scribe arcs, mark out joinery or transfer circle dimensions for routing and cutting. Leatherworking: measure and mark consistent stitch lines, edge outlines, or pattern transfers. General layout and repair: reproduce distances or mark matching parts where consistent spacing is required. What you get A robust wing divider built for repeated, accurate marking and measurement. Hardened points and centered adjustment hardware for dependable performance across projects.
