Eyes and teeth are not the only human body parts that are extremely sensitive and fragile. Our fingers are, too. This trope includes all the nasty things that can happen to them: * Fingers broken one by one; * Fingers cut off; * Fingers shot off; * Fingers bitten off or eaten; * Fingernails pulled off; * Fingernails torn off; * Long sharp objects hammered into the finger bones; * The hand nerves are exposed and pulled to make the fingers move; * Fingers crushed between heavy objects or machine parts; * Any combination of the above.
