The grinding stone wheels of a flour mill are regularly taken out and roughened to maintain their efficiency in grinding grains. Over time, the surfaces can become smooth due to wear, which reduces their effectiveness in crushing and grinding. By making the surfaces rough again, the friction increases, allowing for better grinding performance and producing finer flour. This process ensures consistent flour quality and maximizes the mill's productivity.
In 1880, the cost of a grinding stone would have varied depending on the size, material, and quality. However, generally speaking, a basic grinding stone would have cost around a few dollars at that time.

The two methods of making stone tools are knapping, which involves striking stone to create sharp edges, and grinding, which involves using abrasion to shape and finish the tool. Knapping is typically used for making tools like arrowheads and blades, while grinding is used for tools like axes and grinding stones.

To effectively sharpen and maintain drill bits through grinding, follow these steps: Use a bench grinder with a fine grit wheel to sharpen the drill bit. Hold the drill bit at a 59-degree angle and rotate it against the grinding wheel. Apply light pressure and ensure even grinding on both sides of the bit. Check the bit frequently to avoid overheating and maintain a sharp edge. Use a honing stone to remove any burrs and ensure a smooth finish. Clean the drill bit after sharpening to remove any metal shavings. Store the sharpened drill bits in a protective case to prevent damage.
Sandstone is commonly used as a grinding stone to sharpen tools due to its abrasive properties. Its rough texture helps to remove material from the tool surface and create a sharp edge.
