Marking-Out Caliper Dividers — Carbon Steel, 4 Inch / 100 mm, Jewellery Layout Tool

Accurate work starts with an accurate line. These dividers scribe arcs, circles and centre positions on sheet metal, and step off repeated dimensions so a row of piercings or rivets lands evenly — the layout stage that makes a clean job of cutting with a jeweller's saw afterwards. The hardened carbon steel points hold their edge, so the line stays crisp through a full job.

Flat-profile legs taper to finely ground points, with a bow spring keeping constant tension and a threaded rod with knurled nut for fine, drift-free adjustment. Black-finished legs and satin steel hardware resist workshop corrosion, and the 100mm (4-inch) size suits jewellery-scale and model-making layout.
