It can happen any time: brief contact with the ground and your chain is blunted. That”s when the 2-in-1 EasyFile is a practical tool for sharpening the teeth and depth gauge. Special advantage: the teeth and depth gauge are sharpened in a single action (hence the name 2-in-1 EasyFile). Even if you are an occasional user you will achieve a very good result in only a short time. The EasyFile is suitable for use with .325″, 3/8″ and 3/8″ P saw chains.
