A cat’s paw is a small nail-pulling tool used to remove nails from wood. It usually has one or two curved, V-shaped claws that dig under a nail head so you can pry the nail out.
It is also called a cat’s claw, claw bar, nail puller, or cat’s paw pry bar.
For homeowners, a cat’s paw is especially useful for demolition, trim removal, fence repair, deck repair, and pulling stubborn nails that a hammer claw cannot reach.
How a Cat’s Paw Works
A cat’s paw works through leverage.
The sharp V-shaped claw is driven under or around a nail head. Once the claw grips the nail, the curved end of the tool becomes a fulcrum. You pull back on the handle, and the tool pries the nail out of the wood.
Most cat’s paw tools have:
- Sharp V-shaped claw – Grabs nail heads
- Curved prying head – Creates leverage
- Strike zone – Lets you tap the tool with a hammer
- Second claw or pry end – Gives another angle for pulling
What a Cat’s Paw Is Best Used For
Best for:
- Pulling embedded nails
- Removing nails during demolition
- Deck board repair
- Fence repair
- Pallet or scrap wood breakdown
- Rough carpentry
- Removing stubborn finish nails when surface damage is acceptable
Not great for:
- Delicate trim removal
- Finished surfaces you want to preserve
- Tiny brad nails in painted trim
- Large structural prying
- Replacing a full-size pry bar
A cat’s paw is aggressive. It works well, but it can damage the wood around the nail.
How to Choose a Cat’s Paw
Basic demolition or nail pulling?
Use a standard 8-inch to 10-inch cat’s paw.
Need more leverage?
Choose a longer claw bar or small pry bar with a nail-pulling end.
Working around trim?
Use a thinner, flatter trim puller or molding bar instead. A cat’s paw may leave dents.
Pulling lots of embedded nails?
Look for sharp claws, a durable strike zone, and a comfortable grip.
How to Use a Cat’s Paw
- Position the V-shaped claw around the nail head.
- Tap the tool with a hammer if the nail head is buried.
- Rock the tool until the claw grips the nail.
- Pull the handle back to lift the nail.
- Reposition as needed and continue prying.
- If the nail is long, use a hammer or pliers to finish removing it.
Pro Tips
- Use a scrap block under the tool to reduce surface damage.
- Pull slowly to avoid breaking the nail head.
- If the nail head breaks off, try locking pliers or drive the nail through from the other side.
- Wear eye protection when pulling old nails.
- Use a trim puller instead when you need to save baseboards or casing.
Common Mistakes
- Using it on delicate finished trim — it will often dent the wood.
- Not tapping deep enough under the nail head — the tool slips and chews up the surface.
- Trying to pry too much at once — stubborn nails often need several smaller pulls.
- Using it as a heavy crowbar — it is a nail puller, not a demolition bar.
- Skipping eye protection — old nails can snap or pop loose.
Recommendations
Basic Recommendation:
An 8-inch to 10-inch cat’s paw nail puller is a good size for most homeowners.
Best Value Recommendation:
A cat’s paw plus a flat pry bar gives you a better demolition/removal setup. Use the cat’s paw for nails and the flat bar for prying boards.
Prosumer Recommendation:
A Japanese-style nail puller or high-quality claw bar with sharp, thin claws is better for embedded nails and cleaner extraction.
Best Uses For
- Pulling nails
- Deck repair
- Fence repair
- Demolition
- Removing old boards
- Pallet breakdown
- Rough carpentry
Fixers Club Tip
A cat’s paw is the right tool when saving the nail matters less than getting it out. If you need to save the finished wood, reach for a trim puller first.
