The iron share that cuts the furrow slice and turns it onto the mouldboard — the single costliest piece of iron most farms will ever own, and the reason a village smith is never short of work. It wears blunt against stony ground and must be drawn out and re-hardened each season; a share worn past reforging is sold back for its metal. Ploughs are often held in common and the share tallied separately.
