The Richard S-4-F is a 4" flexible taping knife from the Pro Series line, built for applying drywall compound, taping joints, and setting drywall nails. Its full-tang high-carbon steel blade is heat-treated, tempered, ground, mirror-polished, and lacquer-sealed, and is hollow ground on both sides for smooth, even spreading. The flexible blade conforms to the work surface for clean finishing, while the ergonomic, solvent-resistant polypropylene handle reduces hand fatigue during extended use.
