My dad handed me a hammer when I was twelve and watched me bend six nails in a row. He did not say anything for a while. Then he took the hammer, drove one nail in three swings, and said: “You are fighting the nail. Stop fighting.” Took me another decade to understand what he meant.

Grip the Hammer Correctly

Hold the hammer near the end of the handle, not choked up near the head. This feels less precise at first but gives you leverage. A longer swing arc means more force with less effort. Your wrist should be loose — stiff wrist transfers every off-angle hit directly into the nail, bending it.

Start the Nail Before You Swing

Tap the nail lightly to set it into the wood — just enough that it stands on its own. Now remove your fingers. Your thumb is not a nail holder. Holding the nail close to the head with your thumb and forefinger gives you no precision — it just puts your thumb in the strike zone.

For small nails, push the nail through a scrap of cardboard or an index card and hold the cardboard instead. The cardboard holds the nail upright and your fingers stay three inches away from the hammer. Once the nail is set, tear the cardboard away.

The Swing

Look at the nail head, not the hammer. Your brain already knows where the hammer is — it is in your hand. Focus on the target. Swing from the elbow, not the wrist. A wrist-only swing is weak and inaccurate. The elbow swing gives you a straight arc that lands flat on the nail head.

Most bent nails happen because the hammer face hits at an angle. If you keep your eye on the nail head and swing from the elbow, the hammer face naturally comes down flat.

If the Nail Does Bend

Stop swinging. Trying to straighten a bent nail by hammering it harder just makes it worse. Pull it out with the claw and start fresh. A nail costs a penny. A hole in your drywall from an angry hammer swing costs more.
