How do I remove trim without damaging it?

Use a thin flat bar or dedicated trim puller. Slide the blade behind the trim, pry gently, and work your way along the length. Place a scrap block behind the bar to protect the wall. Score any paint or caulk joints with a utility knife first.

What is a cat's paw and when do I need one?

A cat's paw is a nail extractor with a curved claw that digs under buried nail heads. You strike it with a hammer to get under the nail, then lever it out. Essential for removing nails that are flush or below the surface.

What size pry bar for demolition?

An 18-inch flat bar handles most interior demolition. For heavy structural work, a 30-36 inch wrecking bar provides maximum leverage. Carry both sizes on remodeling projects.

Hand Tools

$5-$15 for basic flat bars, $10-$25 for wonder bars and cat's paws, $15-$40 for wrecking bars, $20-$40 for trim puller sets, $30-$60 for premium demolition sets.

What It's Used For

Pry bars are used for pulling nails from lumber, removing baseboard and trim without damage, demolishing walls and structures, prying apart framing members, lifting heavy objects for shimming, removing roofing materials, scraping adhesive and paint, and separating glued or nailed assemblies.

How to Use

1) For trim removal: Slide the thin end behind the trim piece and gently pry away from the wall. Work slowly along the length. 2) For nail pulling: Slide the nail slot under the nail head and lever the bar to extract the nail. Use a block of wood under the bar to protect the surface and increase leverage. 3) For demolition: Drive the flat end behind boards with a hammer and pry apart. 4) For cat's paw: Position the curved claw over the nail head, strike with a hammer to dig under it, then lever the nail out.

⚠️ Safety Tips

Wear safety glasses and gloves during demolition. Be aware of hidden nails and screws that may fly when prying. Check for electrical wires and plumbing before prying into walls. Use proper leverage — never stand behind a pry bar that could snap back. Do not use a pry bar as a chisel. Inspect for cracks before use — a broken pry bar under load is dangerous.

Maintenance

Clean debris from the nail slot and prying surfaces. Apply oil or WD-40 to prevent rust. Check for bends or cracks — discard damaged bars. Sharpen the beveled edge occasionally for easier wedging. Store in a dry location.
