Sharpen by cutting superfine sandpaper.

Rub your fingers on a sheet of sandpaper laid flat on the bench. This will get off all types of adhesives that you want to get off your hands before washing them.

Can't ever find that emery board when you need one? Cut up different kinds of sandpaper and put small pieces in an envelope. Carry in your purse or stash wherever. This is very handy for that hangnail, or rough spot on your cuticle!

Sometimes I forget to bring along a nail file or emery board when we weekend on our boat. I have found that if I get a little bit of sandpaper and wrap it around something like a toothpick, it will provide enough of an edge for me to file down the ragged edge of one of my nails.
