Which of the following hand tools was the fastest at cutting and harvesting grain from fields?

A scythe has a long blade that lets a worker cut a wide swath of grain with each swing, making it faster for harvesting than a sickle, which cuts a smaller area. A mouldboard plow prepares soil rather than harvesting grain, and a thrasher separates grain from stalks after cutting. The correct choice is the scythe.
