The steel used in chainsaw chains is relatively soft so they can be sharpened with a file.
On nost modern chains the cutter tops and sides are Cr plated and filing the steel underneath the Cr causes it to come off forming a hard edge..
Sometime the Cr plate comes off in bigger flakes than usual like this.

When a chain goes blunt that means the Cr edge has had gone and the edge rounds over like this.
