Review on Osborn International 75116SP Steel Length by Justin Miller

I inherited a lot of rusty files and rasps from my father and I went to clean them, quickly ate some wire brushes and didn't get very far. I then turned to rust removers, but I still needed a good cleaning brush. I knew they existed, but I didn't know what they were called. I finally found this flashcard and it works great. Not only for removing rust from deep flutes, but also for cleaning flutes in softer metal between uses, especially for fine double-cut files. I'll buy a few more to keep, maybe a longer one next time with a bigger handle, or I'll wrap the handle in tape or leather.
