RED DEVIL FLEXIBLE TAPING KNIFE - 6"The 6" blade is the finishing workhorse -- wide enough to feather finish coats smoothly across full-width joints and lay skim coats over patched drywall. Ideal when you want to leave as little material to sand as possible.
- 6" blade width
- Full-tang blade construction
- Solid steel head
- Flexible blade for smooth compound feathering
- Ergonomic handle
- For drywall taping, mudding, and joint compound application
Best For: Finish-coat drywall mud application on butt joints and long seams, feathering wide over patches, skim coating small areas, and any job where the 5" knife leaves too visible an edge. Flex blade smooths compound cleanly to minimize sanding. Use with the 4" for initial taping and step up to a 10"-12" knife for full skim coats.
