A chisel turns blue when on a grindstone due to overheating caused by excessive friction during the grinding process. This heat can alter the microstructure of the steel, leading to a change in color. The blue hue indicates that the metal has reached a temperature high enough to affect its hardness and temper, which can compromise its cutting ability. To avoid this, it's important to use a proper technique and occasionally cool the chisel during grinding.

Why does the edge of a chisel turn blue when sharpening it?
The edge of a chisel turns blue when sharpening due to overheating, which causes the metal to undergo a change in color resulting from a phenomenon known as tempering. As the chisel is sharpened, friction generates heat, and if the temperature rises too high, it can alter the steel's molecular structure, leading to a blue or purplish hue. This coloration can indicate that the steel has lost some of its hardness, potentially compromising the chisel's effectiveness if not managed properly. To prevent this, it's important to frequently cool the tool during sharpening.
