A hammer is not one tool but a family of tools, and each member is shaped for a different kind of work. The claw hammer drives and pulls nails, the ball peen shapes metal, and mallets move parts without marking them. Knowing the differences keeps your work neater and your wrists happier. This guide covers each type, a worked nailing sequence, common situations and the care that keeps a hammer safe to use.
The Everyday Hammers
The claw hammer is the one most people own. One face drives nails, and the curved or straight claw on the other side levers them back out. Curved claws give better leverage for pulling, while straight (rip) claws are handy for prying boards apart.
The ball peen hammer has a flat face and a rounded end. It is a metalworking tool, used for shaping, closing rivets and striking punches and chisels. It is not meant for general nailing.
Mallets and Specialist Hammers
Mallets and Soft-Face Hammers
When you need to tap something into place without denting it, reach for a mallet. A rubber mallet suits tapping furniture joints, flooring pieces and sheet metal. A wooden mallet is the traditional partner for hand chisels. Soft-face hammers with replaceable tips cover the middle ground.
Heavy and Specialist Hammers
- Sledgehammer: a long handle and a heavy head for demolition and driving stakes. Use both hands and keep bystanders well back.
- Club (drilling) hammer: a short, heavy hammer used with masonry chisels and punches.
- Framing hammer: a longer, heavier claw hammer that suits larger nails in carpentry.
- Tack hammer: a small, light head for fine work with little nails.
Quick Comparison
| Hammer | Best for | Avoid using it for |
|---|---|---|
| Claw | Nails and pulling nails | Striking hardened steel |
| Ball peen | Metal shaping, rivets | Driving nails |
| Rubber mallet | Tapping parts into place | Hard driving |
| Sledgehammer | Demolition, stakes | Fine work |
Choosing and Using a Hammer
- Match the head to the job from the table above.
- Hold the handle near the end for power and nearer the head for control.
- Keep the face flat to the work so it does not glance off.
- Check the head is firmly fitted to the handle before every session, and put aside any tool with a loose or cracked head.
- Wear eye protection, since fragments can fly from any strike.
Weight matters. A lighter head is easier to control for long sessions, while a heavier head drives larger nails with fewer blows. Handle material (wood, fibreglass or steel) is largely a matter of comfort and vibration; check the maker’s guide for what the tool is designed to do.
Worked Walkthrough: Driving a Nail Cleanly
Driving a nail seems simple, yet bent nails and dented wood are common. This sequence helps.
- Put on eye protection and check the hammer head is tight on the handle. Support the workpiece on a firm surface or clamp it.
- Choose a nail suited to the wood thickness. As a general guide, the nail should pass through the first piece and grip well into the second without coming out the other side, and the packaging or project plan can confirm what is suitable.
- Hold the nail near the head, or, for short nails, hold it with a pair of pliers or a thin card so your fingers stay clear of the strike.
- Tap lightly a few times with a gentle swing, using the wrist and elbow, until the nail stands on its own. Then remove your holding hand.
- Swing from the elbow with a relaxed grip near the end of the handle. Keep your eyes on the nail head, and let the weight of the hammer do much of the work.
- Keep the face parallel to the nail head. A tilted face makes the nail bend or the hammer slip.
- Stop when the head is flush, or leave a small gap if you will use a nail set to sink it. To avoid hammer marks, finish with light taps or a nail set.
Common Scenarios
- Hanging a light frame: a small claw or tack hammer is easier to control than a heavy one. Check what is behind the wall first.
- Assembling a wooden crate or planter: a medium claw hammer drives nails and pulls the ones that bend. Pre-drilling near edges can reduce splitting.
- Tapping a tight furniture joint: a rubber or soft-face mallet protects the surface. Use a scrap block between mallet and furniture if the surface is delicate.
- Driving fence stakes: a heavier hammer or sledge suits stakes, but swing with care and keep others clear. Check for buried services first.
- Working with a cold chisel on metal or masonry: use a hammer designed for the job, wear eye protection, and check the chisel head for mushrooming, which should be dressed or replaced.
Mistakes to Avoid
- Using a claw hammer on hardened steel. Hard faces can chip, and fragments can fly.
- Choking up too far on the handle. This reduces force and invites mistakes. Hold nearer the end for driving.
- Using a damaged hammer. A loose, cracked or chipped head is dangerous. Retire it.
- Striking with the side of the head. It is not designed for it and can chip or glance off.
- Forgetting eye protection. Nails, chips and debris can strike your eyes.
Quick Troubleshooting
| Symptom | Likely cause | What to try |
|---|---|---|
| Nails keep bending | Off-line strikes or hard wood | Keep the face parallel, tap to seat first and pre-drill hard wood |
| Hammer leaves dents | Missed strikes or head too hard for the job | Use a nail set or a soft-face mallet near finished surfaces |
| Head wobbles on the handle | Loose fit or wear | Stop using it and replace the handle or the tool as the maker advises |
| Wrist or elbow tires quickly | Head too heavy or grip too tight | Try a lighter hammer and loosen your grip |
Care and Upkeep Over Time
Wipe off dirt and moisture after use, and store hammers dry to prevent rust. Check that the head is firm on the handle each time, and look for cracks in wood or fibreglass handles. A smooth face grips and strikes better than a pitted one, so keep the striking face clean. Replace handles that show splits and retire any hammer with a chipped face. Hang tools or lay them flat in a drawer so the heads cannot fall or be knocked.
Glossary

FAQ
Can I use a claw hammer on a chisel?
It is better not to. Steel on steel can chip, and the claw hammer is not designed for it. Use a wooden mallet for wood chisels and follow the maker’s instructions for any striking tool.
What is the one hammer a beginner should own first?
A medium-weight claw hammer covers most household jobs. Add a rubber mallet once you begin assembling or adjusting furniture and fittings.
Why does the hammer keep slipping off the nail?
Oil, dirt or a worn face can cause slipping, as can a tilted swing. Clean the face, keep it parallel to the nail head, and replace a badly worn hammer.
How heavy should my hammer be?
That depends on the work and on you. Lighter heads are easier to control for fine tasks, while heavier ones suit bigger nails. If it tires your arm quickly, try a lighter one.
How do I remove a bent nail?
Use the claw and slide a scrap of wood under the head to protect the surface and improve leverage. If the nail resists, use pliers instead of forcing the hammer.
The Short Version
Claw hammers handle nails, ball peen hammers shape metal, mallets tap without marking, and sledges do heavy work. Choose the head for the job, keep it tight on the handle and wear eye protection. Always follow the maker’s safety instructions.
