The fork turns a bar into a nail puller
A crowbar’s split end is more than a distinctive shape: its narrow prongs can slide beneath a nail head. Once the head is caught in the fork, the bar gives the user leverage to pull the nail out. The tool’s name reflects that forked, footlike shape rather than the bird’s behavior.
Why the shape matters
Pulling a stubborn nail by hand means gripping a small head and overcoming the friction holding its shaft in wood. A crowbar changes the task into a lever action. The wood beneath the curved end acts as a fulcrum—the point the bar pivots against—so pushing on the handle can produce a much stronger pull at the nail.
That makes the name a compact description of the tool’s working end: the fork catches, the bar pivots, and the nail comes free.
