Here I will show you how to use rocks to make tools. The important thing is to have some knowledge of the different types and kinds of stone. Here we will be looking for chert obsidian novaculite and agate. Chert is the most available quartz there is. It can be found from coast to coast and as far north as Canada. The type of rock we will be looking for will have a shiney surface like glass. In fact glass is a good type of material to make tools out of.
Materials are easier found in stream beds especially on gravel bars where different rocks are piled up from high water. Look for white rocks thats a good identifier of chert.Here is a piece of really good chert or flint that I found that had been worked by a native American. It shows the near perfect chipping or fracture of a professional knapper. Look at the perfect chip that runs the entire length of the chert making the rest of the process easy.
I can now show you how this is done. After you have found your material an almost razor sharp knife can be made pretty easily by striking the edge with another rock as demonstrated. I use a hammer here to show the striking area and angle of the strike. Strength is not the key here but the angle and placement of the strike. Stroke downward and outward and pull the chip away from the rock.
The chips are as sharp as any knife in the drawer and a pointed piece here could be used for a punch.
Here are some examples of different kinds of material. The black is obsidian the white is chert and the colorful chips are novaculite or agate.
Here is an example of what you can make from this material with knapping tools. I will show you how you can use tools you can find to make some points in the next installment.
