Wet grinding wheels are often used for sharpening knifes, since one
definitely doesn’t want to heat up a knife and thus change its hardness.
Wet grinding wheels are also great for grinding unicycle parts which one
doesn’t usually want to change the hardness of.
An alternate to a grinding wheel designed for wet grinding is using a
regular grinding wheel and dipping the part to be ground in a water
bucket every second or two. The longer one waits between successive
grinds, the less the part will heat up and leave hardness alone.
