钉子
A nail is a thin piece of metal with one pointed end and one flat end. You hit the flat end with a hammer in order to push the nail into something such as a wall.
If you say that someone is as hard as nails, you mean that they are extremely tough and aggressive, either physically or in their attitude towards other people or other situations.
