What is a riffler file?

A riffler file is a specialized tool used in metalworking, woodworking, and other crafts for shaping and finishing materials. It features a unique double-ended design with one end typically having a flat surface and the other a curved surface, allowing for precision work in tight spaces or intricate shapes. Riffler files come in various shapes and sizes, making them versatile for tasks like smoothing edges, refining contours, and achieving detailed finishes. They are particularly useful in applications where standard files may not reach effectively.
