What it does
Flexible 6" (152 mm) joint knife with a high-carbon steel blade that is ground, polished and clear coated. The Hammer Head® sets drywall nails. The nylon handle resists wear, abrasion and common paint thinners.
How to use it
- Press to load and bed, then ease off to level; keep the blade fairly flat to the wall.
- Apply thin layers, each coat wider than the last, rather than one heavy pull.
- Tap the striker to set a fastener flush; do not swing it. Wash the blade before the mud dries.

Common questions
Standard flex or the ExtraFlex 02852?
Standard flex builds and presses coats. The ExtraFlex is the limber finisher for the last wipe. Both are 6" wide.
What is the Hammer Head for?
Setting popped nails and screws so you can coat the dimple with the same knife.
Can I do the final feather with it?
It blends well. The 02852 does the dead-flat finish pass.
Will it scrape?
No. The blade is flexible. Use a stiff blade to remove material.
Need it for a different job?
- 6" SuperFlexx 02852For the final feathering pass
- 3" Flexible 02355For small patches and nail holes
