Compatibility and working details

When to choose it
The four-inch working edge leaves more clearance beside an outlet or trim than the six-inch knife from the same range. Compare the gap around your patch, including space to angle the tool as you place compound. The maker describes a hollow-ground area on this stainless blade to control where it flexes.
This version uses a polished all-metal body. Compare the four-inch soft-grip model if you want the same working width with a different grip. For broader feathering, choose a wider knife that still clears the area.

Questions about this product
How is it different from the all-metal six-inch knife?
The four-inch edge fits a tighter area. Compare the wider tool if you need more blade contact on the same pass.
What if I want a different grip material?
Compare the four-inch soft-grip version. The contact width can match while the grip changes.
Is this enough to feather a long seam?
Plan the feathered area and compare a wider taping knife if you need more room across the seam.
