Scythes are a type of agricultural tool used for harvesting crops. They consist of a long curved blade attached to a handle, and are used to cut grass, grain, and other vegetation. The term 'MOWS' refers to the act of cutting grass or other vegetation with a scythe, while 'REAPS' refers to the act of gathering the cut vegetation. Scythes have been used for centuries as a way to efficiently harvest crops, and are still used in some parts of the world today.
