The FLEX IN® Curved Wire Scratch Brush (Knife Brush) is engineered for aggressive cleaning and surface prep work on metal, masonry, and weld seams. Built with a narrow, knife-style curved metal spine, it allows easy access into tight grooves, corners, and narrow channels that standard flat wire brushes cannot reach. Dense brass-plated crimped steel bristles deliver high scrubbing power while resisting premature wire fallout. Fitted with a contoured high-visibility yellow plastic handle featuring knuckle guard protection and an ergonomic anti-slip grip for comfortable, high-leverage scrubbing. Packaged individually in a protective hanging blister card.

Key Features & Standards

Brass-Plated Steel Bristles: High-density wire fill provides heavy-duty abrasive action while offering corrosion resistance.
-
Ergonomic Guarded Handle: Molded plastic handle includes a finger guard to protect knuckles during heavy scrubbing motion.
