What is a putty knife used for?

A putty knife is a flat, hand-held tool used for applying fillers, smoothing over surface imperfections, and scraping away old material such as paint or loose compound. It is an essential tool for tradespeople and DIY users alike, especially when working on surface repairs and finishing.

Putty knives are commonly used in plastering repairs, joint filling, surface preparation and general decorating tasks where accurate edge control and detail work are required.

Putty knife vs drywall knife

While both tools are used in finishing and repair work, putty knives are typically smaller, more rigid and used for finer detail and patch repairs. Drywall knives, on the other hand, usually have a wider blade and are used for spreading compound across larger areas.

If you’re working on smaller touch-ups or detailed work requiring greater precision, a putty knife is often the ideal choice.

Flexible blade – when is it best?

A flexible blade is ideal when working on uneven surfaces or when you need smoother pressure control during application. Increased flexibility helps distribute pressure evenly and reduces the risk of drag marks or surface damage.

Benefits for smooth finishing

• Improves surface smoothing for final finishes
• Helps maintain even pressure during applying fillers
• Enhances control and precision on delicate work
• Offers better adaptability on irregular surfaces
