Review on Sharpen Your Tools With HTS 101I0 6Pc 180Mm / 40-600 Grit Diamond Flat File Set by Jeff Hall

This is a set of small diamond files with 6 different levels of coarseness. I have primarily used them for making jewelry and some other precision metal work. These have worked well for me for about 6 months so far.I used them to get an edge on a knife that had been badly abused and then followed that up with whetstones. Rescued the knife.The files are small and that can be difficult to tell from the images without something in the picture for reference. The actual part that does the filing is about 1/4" wide by not quite 3 inches long. The total length is about 8 inches.There are certainly better files available, but I haven't seen any in this price range. For what I needed, these have performed well.
