When a carpenter hammers a nail absorbed in the work, she is not aware of the hammer. She is aware of the joint, the board, the project the joint serves. The hammer has withdrawn from consciousness, become transparent to her intention, invisible in its function. It is only when the tool breaks—when the hammer head loosens, when the nail bends—that the tool becomes present-at-hand, an object of conscious inspection with properties and limitations.
