Review on 140Mm/150 Grit Diamond Needle File Set - 10 Piece HTS 101E0 by Abhinav Drury

i would give it a 5 but the picture shows flat handles, and mine are round, the rubber coating comes right off and it's uncomfortable in my hand. I haven't found a use for the 40 grit, as the texture is like very course beach sand. Everything I put the files through they survived just find. One of them serves as a file for metal so my junk DMT files can do the fine sharpen (these cheaper looking files are better than DMT files any day).You get about 3" or so of usable grit, and the edge also have diamond. The finest one makes a nice nail file, and the middle ones are good for callouses, just make sure to put a better handle on it, I used cork.
