The stone tools that characterize the Jōmon period were used for hunting, farming, building, and cooking. Hunting tools included flint arrowheads and stone spears. Farming tools and other implements included stone spatulas, polished stone axes, stone spindles, and whetstones. Cooking tools included stone spoons, stone plats, grindstones, and beating stones. The polished stone axes came in various sizes, some used to cut down trees, and others such as hatchets or chisels. The stone spoon was a tool used for the dismemberment of animals caught, while the stone plate, grindstone, and beating stone comprised a set for breaking down and grinding nuts and roots.
