The 4" blade is the go-to size for embedding drywall tape over butt joints and inside corners - narrow enough to work in tight spaces, wide enough to lay tape flat in one pass.

• Blade width: 4"
• Flexible high-carbon, precision-ground steel blade
• Lacquered blade prevents rust
• Blade extends through the handle for strength
• Black nylon, solvent-resistant handle
• Brass-plated solid steel nail-setting head for setting drywall nails and other hammering jobs
• Red Devil 4200 Professional Series
• Manufacturer part: 4214

Best For: Embedding paper or fiberglass drywall tape into joint compound, cutting in inside corners, applying the first coat of mud over butt joints, and small patch and repair work. The flexible blade lets you feather compound smoothly at the edges to reduce sanding. For finish coats on wider joints, step up to the 5" or 6" size.
