collect information about stones is tools and weapons
Answers
Answer:
Blade cores were chunks of sharp rocks used as the source for other types of tools. Pieces of stone would be flaked off of the core, in the shape of thin, rectangle-like chips; these were crafted into knives, scrapers, spear blades, hand axes and other tools and weapons.
Answer:
Humans began crafting tools and weapons from stone about 2.5 million years ago. Although early implements were utilitarian in appearance and basic in function, they paved the way for the development of the complex technologies humans use today.
Hammerstones:
Early humans did not so much craft hammerstones as they did select them for size, strength, and weight. These massive tools were used to create other tools, such as choppers, which was accomplished by whacking hammer stones against other stones, to chip off flakes of material. Later developments in the Acheulean era saw early humans choose specific types of stone from which to make other tools. Stones like flint, and other "flaking" stones like quartz, could produce a sharp, cutting edge after being struck by hammerstones. Similarly, over time humans learned that hammerstones of different sizes and hardness yielded better results for making other primitive tools.
