A nail-pulling tool has a two-piece proximal handle pivotally joined with a two-piece distal jaw by a pivoting means. The distal jaw is operated like a standard hand tool with compression of the handle causing the jaw to close, and vice-versa. The distal jaw has an elliptical surface so that with the distal jaw resting on a work surface and closed about a nail protruding from the work surface, and with the handle laying adjacent the work surface, raising the handle away from the work surface in an arc, causes the nail to be pulled from the work surface at an ever increasing rate. Axially oriented jaw teeth provide improved gripping and a pair of tongue and groove opposing surfaces enable cutting and further improved gripping. A hammer surface enables driving of a nail into the work surface rather than pulling it out, and a claw element enables pulling a nail head up so as to be better gripped by the tool. The tool is ideally designed for pulling a bent nail partially upward, straightening it, and then hammering it back into the surface in a more correct and improved manner for accomplishing its fastening task.
