A half-round steel file is a multi-purpose abrasive hand tool designed for smoothing, deburring, and shaping both flat and curved surfaces on metal, wood, and plastic. Forged from high-carbon hardened steel, it features a unique cross-section with one flat side for flat surfaces and one rounded side for concave contours and broad internal curves. Key features include cross-cut teeth for efficient material removal, a tapered tip to access tight spaces, and an ergonomically molded yellow plastic handle that delivers a firm, comfortable grip and precise control during metalworking, woodworking, and general fabrication projects.
