The Crescent Nicholson® 21839NN Mill Bastard File is a premium-quality, American-pattern file designed for sharpening mill or circular saws, draw filing, and finishing metals. With a 10-inch file length and single-cut bastard teeth, this tool delivers a perfect balance of aggressive material removal and smooth finishing, making it a staple in the toolkits of machinists, metalworkers, and maintenance professionals.

Crafted from high-carbon steel, this file features a rectangular cross-section with two square edges, allowing for precise filing of flat surfaces and the creation of grooves with consistent width. The file tapers slightly in width toward the point, improving access in slots and tight spaces, while the single-cut texture on both the faces and edges ensures a clean, controlled finish.
