What Customers Are Saying

Customers overwhelmingly praise this putty knife for its effectiveness and affordability across small repair tasks. Reviewers consistently highlight smooth results on spackle application, wallpaper removal, and drywall patching, with many noting it performs as well as expensive brands. The flexible steel blade handles tight spaces with ease and minimizes sanding. Most appreciate the exceptional value, describing it as durable yet inexpensive. The compact size suits detailed work and small hands well. A few mention sharp edges as a safety concern or rare rusting, though most still recommend it despite these minor trade-offs.

This is the best price I have seen in a few years

Would Recommend

This putty knife was used to spread a bonding and sealing compound that is similar to mastic. It has the right flexibility and width for the job and to fit the container that held the compound, plus it also worked with a similar compound that was applied from a caulking gun.
