FAQs
Is the RPK03-SS flexible?

Can I use this for applying joint compound?

Will the blade rust if used with water-based fillers?
The stainless steel construction is highly resistant to rust, but you should always wipe it dry after use.
Can I sharpen the blade if it gets dull?
Yes, you can carefully use a fine sharpening stone to maintain the edge, but be mindful not to alter the precision taper.
Is this tool suitable for outdoor use?
Yes, its rust-resistant properties make it suitable for outdoor renovation tasks.
Troubleshooting
Blade has minor surface rust
Use a fine-grit abrasive pad or specialized stainless steel cleaner to gently buff the affected area.
Stubborn paint buildup on the blade
Soak the blade in a suitable paint solvent for a few minutes, then wipe clean with a lint-free cloth.

Setup, Compatibility & Care
No specialized setup is required; the Ragni RPK03-SS is ready to use straight out of the packaging. To maintain the integrity of the tool, wipe the blade clean immediately after each use to prevent any chemical residue from compromising the stainless steel finish. If you are using harsh solvents for stripping, ensure they are compatible with the metal. Store the knife in a dry tool box or hang it by its handle to protect the edge from accidental nicks. Avoid using the knife as a pry bar or a screwdriver, as this may damage the precision taper of the blade.
