Why does a hammer have claws when its main job is to drive nails? That curved, split metal end is more than a simple hook—it’s a clever piece of engineering designed to grip, lift, and remove nails using mechanical advantage. In this episode of History of Simple Things, we uncover why claw hammers are shaped the way they are, how the claws create leverage, why they’re split into two points, and how one simple tool became capable of both driving and extracting nails. What looks like an ordinary hammer is actually a compact lesson in physics, force, and practical tool design.
