Choosing a saw file
Tooth pitch is usually given as teeth per inch (tpi). A file about twice the tooth height spreads the wear best. A single-cut file gives a slightly finer finish and is the usual choice for saw sharpening.
Sequence
1. Joint the teeth so they are all the same height, ideally with a jointing tool.
2. Shape the teeth.
3. Set the saw.
4. Sharpen the teeth.
Sometimes sharpening alone is enough, but a very dull or second-hand saw needs the full sequence.
