Warning: The following post describes self-harm. Don’t try it at home.
I don’t cut my nails, I file them. I do cut my fingers though. You know the rough patches of skin that form at the fingertips, all the way around the nails? Well, I hate it. And I cut it with sharp scissors. Why, yes, I’ve heard of hand cream (speaking of which, I’m just massaging a generous amount of it into my hands) and of softening oil. But that’s nonsense.
Nothing delivers perfectly smooth fingertip skin as well as just cutting the hard bits off. Of course, you have to wait a day or two until it stops bleeding for the effect to fully manifest itself, but it’s totally worth it. There’s also a bonus to it: I’m gradually erasing my fingerprints, in case I needed to commit a crime and remain unidentified.
Other than that, I don’t cut myself. I have a cat to do it for me.
