When hanging a picture or fixing a loose board, you pick up a hammer. Its solid metal head delivers the force needed to drive a nail into place.
A closer look reveals the head's distinct shape: one broad flat side paired with a curved, forked claw on the opposite side. This division equips the tool for two linked actions central to everyday repairs.
The flat face offers a wide, smooth surface for striking. This design directs impact squarely onto the nail, guiding it straight into material without deflection.
How the Claw Enables Removal
The claw side curves outward and splits into two prongs. Slid under a nail's head, it creates a fulcrum point. Rocking the hammer back applies steady upward force to extract the nail smoothly.
These paired features on the head support the full sequence of nailing: embedding fasteners and retrieving them for repositioning. The hammer channels effort into both driving and prying with precision.
This shaped head turns the hammer into a tool built around the realities of assembly and adjustment. The form follows the forward and reverse motions it must perform.
