Frequently Asked Questions (FAQ):

Q: Are these knives suitable for professional drywall finishing?
A: While they are designed for light to medium-duty work, they are best suited for patching, minor drywall finishing, and areas where a rust-free, disposable option is preferred.

Q: Can I reuse these tools, or are they disposable?
A: These joint knives are reusable and can last through many jobs with proper care and cleaning, though some professionals use them as disposable tools on messy or quick-turnaround projects.

Q: Can they be used with solvent-based compounds?
A: They are best used with water-based materials like joint compound, filler, or lightweight plaster. Solvent-based materials may degrade plastic over time.

Q: Do the plastic blades provide the same finish as metal ones?
A: While plastic knives are slightly less rigid than stainless steel, they still provide a smooth finish, particularly for basic compound application, patching, and sanding prep.
