The cultivation of cereals is closely related to the sedentism of man. The first farmers used flint stone sickles as harvest tools, which gained a typical “sickle gloss” from cutting the crops. Later, sickles were made of metal, yet their form and function have essentially not changed to this day. As early as the Stone Age, grain was ground and then baked to make bread. However, it is not clear if the so-called baking plates were actually used for this, as some archaeologists believe.
