File this one under sharper multi-tool blades
While cutting out damaged molding in my home using my oscillating multi-tool, the tool's blades began to dull, burning the wood after only a few cuts. Because the blades cost around $10 each, and throwing out blade after blade seemed wasteful, I decided to resharpen them. I bought a set of Japanese saw files (no. 06Q10, 800-225-1153, woodcraft.com) for the job, and soon had all my blades sharpened.
