I've been biting my fingernails since I can remember. I picked up some nailfiles today, but mostly for my toes. My big toes get the most painful ingrown toenails I've ever experienced, and I can't avoid them at all if I cut them. And yes, I do cut them right, I always take extreme precaution when doing that, yet I never win. So I started to just cut the other 8 and file down the big 2. Well since I have 30 files here, I started using one for my fingers, and now I feel as though I have nothing TO bite even if I wanted. I think this may be a great tool in the road to stop biting my nails, even if it is kind of girly.
