How do you sharpen a sword with a grindstone?

To sharpen a sWord with a grindstone, begin by securing the sWord in a stable position to ensure safety. Then, hold the blade at a consistent angle—typically around 20 degrees—against the rotating grindstone. Apply gentle pressure and move the blade back and forth along the stone, allowing the grit to remove material and create a sharp edge. Periodically check the blade's edge for sharpness and ensure it remains cool to prevent overheating and damaging the steel.
