I always try to think of ways to use things as much as possible before tossing them out. I recently realized a great use for partially worn out fingernail emery boards. I keep them in a container and use them when I refinish antique furniture. You can pop off just the length you need and they are thin enough to get into the crevices of detailed pieces, and they are so much easier to handle than regular sandpaper.
This page contains the following solutions.
When starting to use a new emery board, start at one end and just use about an inch and a half for your nail filing. As that section gets dull, then move along another inch and a half.
