The 10-inch Cobra QuickSet water pump pliers from Knipex Tools have a slide-and-lock push-button system for repetitive use. The lower jaw slides up to the object and provides a precise fit with a squeeze of the handle. The pliers, made from high-alloy German chrome vanadium steel, have a 2-inch gripping capacity and a pinch guard to protect hands and fingers. The hex-shaped gripping surface with hardened teeth (61 HRC) can fit around any round, square, hex or flat object. 847/398-8520; www.knipex-tools.com.
