Handsaws are designed to provide years of good service. However, by wiping the entire surface of the saw blade with an oily rag, you will maximize your saw’s performance and extend its life. Many hand saws come with a protective tooth cover. Don’t throw this away. It will protect the teeth from any harm that could occur in a busy workshop. If you can’t find this cover, cut and slice open an old garden hose and use it to cover the entire length the blade.
