Frequently Asked Questions (FAQs)

1. Are plastic or metal putty knives better?

Plastic blades are often disposable and do not stand up well to continued use. A better-constructed blade is made from ground and polished carbon steel. However, although the carbon steel is more durable, it may rust if not properly maintained. The premium version of a putty knife blade is made of stainless steel.

2. What are putty knives called?

A spackle knife (called a scraper in British English, also known as a spatula in American English) is also commonly called a "putty knife", and is used for scraping surfaces or spreading material such as plaster in various construction trades.

3. What are putty knives used for?

Chances are you have one or more standard putty knives in your toolbox. Putty knives are used to apply putty or surfacing compound into cracks and nail holes, patch divots with wood filler, and spread drywall mud into drywall joints and seams. Putty knives come in a variety of sizes.

4. What is the difference between a putty knife and a scraper?

While they both look the same, scrapers have a stiff blade that is too stiff for the efficient application of compounds. Putty knives, on the other hand, have a thinner blade that is too flexible for scraping.
