Finger forgotten
I have cut my nails somewhere around 700-800 times assuming I need to do that every two weeks. I have extremely strong nails. I've hardly ever broken one. That's why I need certain special conditions whenever I need to cut them.
The best time to cut them is after sauna. The hest and humidity makes them soft enough to be able to cut them comfortably. Even then, the operation is something that needs intensive focus. Being just s bit sloppy could lead into a nasty results.
