All in one!
LOVE this tool! I didn't realize there were so many options to this tool. From traditional distressing, where you distress the edge of your matts or photos (with the side of the tool) to sanding (replacing my sandpaper file) for the perfect edge and finally the bottom of the tool exposes yet ANOTHER type of distressing tool, a wire brush! Finally, it comes with another, heavier interchangable head in order to get a deeper distress. Overall, great tool!!!
