Review (5/5): These work great.
I have used the nail scrapers, I guess that is when they are called, the most, and they work great. The other ends, one is sharp and I used that yesterday, it does what it is supposed to do. It accurately cut through some old polish. The other end has a kind of pick on it and it works great for getting stuff out from under your nails. I finally used the scissors and these are very precise, use caution, as they will cut off anything you put between the cutters. These are like having surgical instruments to work on your nails.
