Richard Ergo Grip Series Flexible Carbon Steel Joint Knife - 3"

The Richard Ergo‑Grip Series Flexible Carbon Steel Knife is a premium‑grade finishing tool engineered for high‑performance drywall taping, patching, and compound application. Designed with professional ergonomics in mind, the Ergo‑Grip series combines superior blade flexibility with a comfort‑focused handle system to reduce fatigue and enhance control during repetitive finishing tasks.

At the core of the design is a flexible high‑carbon steel blade, measuring 0.05" to 0.065" thick, offering the perfect balance of flex and strength. Each blade is full‑tang, heat‑treated, tempered, ground, mirror‑polished, and lacquer‑sealed, ensuring long‑lasting durability, resistance to corrosion, and consistently smooth compound application. The hollow‑ground blade design on both sides delivers exceptional distribution, making it ideal for feathering, taping, and finishing.

The distinctive Ergo‑Grip handle is made from soft, rubber‑like Santoprene, which provides superior grip, cleans easily, and resists solvents. Its ergonomic design minimizes pressure points, reduces hand strain, and maximizes precision. Features such as a broad protective hilt, recessed finger angle, and built‑in finger cavity offer unmatched comfort and slip protection, making this one of the most advanced putty knives for demanding finishers.
