What does grindstone mean?
A grindstone is, literally, a wheel made of stone that is used to grind or sharpen tools and other materials. Its figurative meaning is more common today: to keep someone's nose to the grindstone means to compel them to work hard and continuously, while describing work as being under the grindstone suggests that it is exacting and relentless. The expression comes from the physical action of holding a tool against a rotating grindstone, where a person naturally brought the face close to the wheel. The word can therefore describe either the tool itself or the burden of hard work represented by it. Its imagery is strong and memorable, giving ordinary English an unusually vivid sense of sustained pressure and toil.
