The process of early age tattooing was long and painful. Some of the first tools used in tattooing were made of bone, stone, or wood. There were mainly two types of tools used in the process of making most tribal tattoos: a small rake-like shaped tool, and another plain rod with a flat surface. The rake-shaped tool was used to make the design of the tattoo. It would first be dipped into its ink or dye, and then punctured into the skin by being tapped by the flat tool. Other processes consisted of scratching the skin and then rubbing in the ink.
