Primitive farmers used a stone axe, a wooden hoe, and a sickle. The stone axe consisted of a wooden handle and a sharpened stone tied to it with leather belts. The wooden hoe was a stick with a twig. The sickle was made of wood or bone, splitting them slightly and inserting sharp stones into the cleft. With an axe, primitive people cut down trees to clear a plot of land for farming. With a hoe they dug up the ground, and with a sickle they cut off the ears of grain when they were ripe
