What it does
Flexible 6" (152 mm) stainless steel joint knife. The blade is double hollow-ground for the flex point, and the grip has overmold cushioning. Stainless resists rust.
How to use it
- Press at the handle center to leave the joint slightly proud for sanding; press a corner to feather that side out.
- Lay compound at a low angle and raise the blade to strike it off level.
- Rinse after use and dress the edge with a file if it dents.

Common questions
Does stainless feel stiff?
Not this one. It is double hollow-ground, so the flex point behaves like a good carbon blade.
Do I have to dry it?
No. Rinse and rack it.
6" or wider?
A 6" covers tape, spotting and patches. Buy a taping knife alongside it for fill and skim coats.
How is it different from the full-metal 06879?
Same width and steel. The 06878 has a cushioned bonded grip. The 06879 is one continuous piece of stainless with no crevices.
