However, it is not flat but a Tobleroneform.
It's annoying and does not fit all.
Humans have two hands. Adjusts the fine grit, when I hold the file with the right and the left hand file nails, so I have the coarse grain of the back when I take the file in the left hand to right to file also. But I want to continue the fine side. For that I have to turn the page files. In the flat form no problem. Here I have to make do with the thick end of the triangular shape. Cumbersome, unwieldy files with poor results.
