The precision woodworking compass is forged from carbon steel, with overall heat treatment, wear resistance, durability and long service life.
The forged high-carbon steel legs feature hardened points for precise marking of the workpiece and precise fine adjustment by simply loosening the lockable wing and tightening it.
The leather compass is a useful measurement transfer tool for measuring the internal size of round stock or irregular-shaped objects. Also great for scribing circles into metal, dividing lines, drawing arcs, line segments, geometry drafting, etc.
Smooth surface and burr-free, accurate measurement, can be used for a long time and not easy to loosen.
