6 different grades of flat files. I used them extensively for a project (on steel & aluminum) and they have held up extremely well. No breaking, no bending, no loss of grit. Great set to have on hand.

I always misplaced or lost my hook sharpener, so I put couple of these in my tackle box, great for sharpen hooks, I'm sure they're good for many use.

Contractor said the blanket style Ikea handles couldn't be cut to the size I wanted. I did it myself and then used these files to smooth out the slightly rough edges. Great little tools.

I didn't expect much from these inexpensive files and the construction looks "cheap", but they work extremely well. I use them for making bassoon reeds. The coarser grits remove material quickly in a controlled way and the finer grits make things smooth. These are my first diamond files and I like them better than steel files. They don't tear the wood, they're slow to clog, and when they do, they can be rinsed off with water. I bought two additional sets to give to other double-reed…

I had some cast iron free weights delivered that had some jagged edges and rough spots in the grips. These files made quick work smoothing these defects out. Worked much better than I expected.

I find myself reaching for these files a lot. I wish they had a thinner edge to allow getting in even tighter spots, but that's nitpicking. A great addition to my shop to be sure.

Ordered these to file chips on glassware and dishes. Seems to do a pretty good job; however, I haven't used them too much.

Been looking for a 40 grit diamond file, that wasn't really expensive, for a long time. This kit not only has the 40 grit (for really fast metal removal - for shaping operations), but also perfect gradation of grit to the very fine 600 grit file. Using this spectrum of grit grades, I've been able to roughly shape hardened knife blades and leatherman tools, then -going through the entire grit range of files- end with a polished (ending with the 600 grit file) finish; which can be made mirror…
