Frequently Asked Questions (FAQs)

1. What type of putty knife should I use?

We found that the best general purpose putty knife is the Craftsman 1½-inch Flex Stainless Putty Knife. It's the best size for filling small holes and cracks, it has an easy-to-clean stainless steel blade, and it has a long, ergonomic handle that makes the tool comfortable to hold and use for extended periods of time.

2. What is a putty knife used for?

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.

3. Is plastic or metal putty knife 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.

4. Are plastic putty knives any good?

Because they are made from plastic rather than carbon or stainless steel, these putty knives won't last as long, but they are still durable and a great value because you get three different types of knives in one set. This includes a 1.5-inch putty knife, a 3-inch spreader, and a 6-inch taping knife.
