What distinctive feature does the sharp edge technology provide when grinding red ochre?

The distinctive feature that sharp edge technology provides when grinding red ochre is the production of a sharp edge. This process is significant as it allows for greater precision and effectiveness when using the ochre, whether in artistic applications or for other purposes such as tool-making or creating pigments. The sharp edge increases the efficiency of applying the pigment, making it more versatile for various uses. Additionally, having a sharp edge can enhance the quality of the ochre being processed, making it suitable for detailed work. Hence, this characteristic of sharp edge technology is crucial in both prehistoric and contemporary contexts for its functional applications.
