Sand deep crevices
If you are refinishing an elaborate piece of wood such as turned table legs or chair spindles, you can use emery boards to gently smooth those hard-to-reach crevices before applying stain or finish. These filelike nail sanders are easy to handle and provide a choice of two sanding grits.
Prep seeds for planting
Use an emery board to remove the hard coating on seeds before you plant them. This will speed sprouting and help them absorb moisture.
Save your suede
Did somebody step on your suede shoes? Or worse, spill some wine on them? Rub the stain lightly with an emery board, and then hold the shoe over steam from a teakettle or pan to remove the stain. This works for suede clothing too.
