In general wing compasses and dividers are favoured for robustness while the bowspring type are considered more precise and adjustable.Beautifully forged and hand ground in Saint-Etienne, Ledin compasses, dividers and calipers may cost a little more than cheap mass produced ones but their rigidity, accuracy and reliability put them in an altogether different league.Ledin wing compasses and dividers are properly constructed with a heavy duty sprung and riveted box hinge, as you can imagine this arrangement is substantially stiffer than a simple overlap.The maximum spread (capacity) is equal to the total length of the arms for an opening of 60° in this case 190mm.Pencil holder ∅ 8mm
