Plowshare

In

The plowshare itself is often a hardened blade dressed into an integral moldboard (by the blacksmith) so making a unified combination of plowshare and moldboard, the whole being responsible for entering the cleft in the earth (made by the coulter's first cutting-through) and turning the earth over.

In well-tilled terrain the plowshare may do duty without a preceding coulter.

In modern plows both coulter and plowshare are detachable for easy replacement when worn or broken.
