Abstract: A chain saw file case is arranged for the mounting and securement of a chain saw file to protect the relatively brittle file for maintaining its integrity and continued use. The case includes a cap threadedly securable within a base, with the cap and base coaxially aligned and the base including an alignment bushing formed with a conical interior surface at a lower terminal end thereof, with the base further including a tubular magnet mounted adjacent an upper terminal end thereof to accommodate and attract various metallic debris resulting from use of the file structure.
