This tool's name is End scraper and it looks like a rain drop shape. The purpose of this tool is to abrade the fur and skins from animals. However, they might have can use other materials for ripping fur and skins from animals, such as wood or bone. According to anthropologists, this tool wasn't the only hand hold tool. End scraper can have a wood handle on it. In addition, this was a very useful tool for making clothing and shelter with animal's skin. This fits into my theme, because my theme is tools, and this is also a tool, and its duty is to scrape animal's skin/fur. I see a 3 rocks, left rock is rain drop shaped rock, and its color is brownish yellow. The middle rock is attached to a wood, and the rock is much smaller than the other two. Right one is a similar size with the left end scraper. However the color is grey. I think it will take some time to rip the tough and thick animal's skin. I wonder people in Stone Age use this tool to cut the tree or in a other purposes. This source is reliable because this source is related with science, and my theme is pretty connected to the science therefore this is reliable.
Flint is a very hard rock. Flint was mostly find in the streams and sea. In addition, this was used several people in Stone Age. This was used to create tools and weapons for 2 million years. It is also used to produce sparks and gemstone. Our ancestors knew how to use this tool and how to create knife, spear points, arrowheads, scrapers, axes, drills, and other tools using a methods, which is flintknapping. If some tools or weapons breaks, those were fixed by flint. I consider this as a tool because tool has a purpose, such as scissors has a job of cutting an object. This has variety of purpose, therefore I will say that this is a tool. I see shape which is oval, sharp points on the side, and brownish color. I think this might used as a weapon because it has a sharp point. I wonder if some flint was made out of wood, not with a rock. I think this cite is reliable, because it's related to the geology organization, and flint is also related with it.
Its purpose was to chop meat, rip skins, cut wood, dig holes, hammer bone or wood, and fight against wild animals. Hand axe's shape and its size depends on the culture, geological zone, and time period. However it still had a similarity which is this tool can fit on your hand. The reason that this is a tool is because hand axe has several purpose and this can made our ancestor's life more accurate. I see grey rocks, they are little long. I think this was used by almost everyone during that time period because I think it's pretty light and easy to make. I wonder how did ancient people came out with this idea. I think this source is reliable because it's linked to the biology so as my tool.
This tool is called pebble chopper. Pebble chopper was the first tool for cutting. In addition, this was the oldest tool which were created by our ancestors. It's shape is round, structured out of pounder and other similar rocks. Not only for cutting, it can also us hunting knife, dig roots, and so on. Pebble Chopper is my part of my theme, because this is man made and used by our anestors different ways. I see a person holding the pebble chopper. It's shape is pretty random, some holes are in it. I think pebble chopper was not easily to be rotten, because it was made out of rock, so we can find this more easily. I wonder the process of making this tool.
