A chainsaw sharpener is used to keep your chainsaw sharp. Unlike the manual filing that takes so much time and effort, a chainsaw sharpener is the quickest way to keep your chainsaw blade sharp.
There are two basic types of sharpeners- manual (files and bar) and electric. The manual chainsaw sharpener may offer precision and control but it takes time. The electric version provides almost the same result as its manual counterpart but at a shorter time.
The small rounded files are the most affordable type of chainsaw sharpeners. Most electronic sharpeners have tiny rotating saws and grinding discs. These discs are typically adjustable to get the proper angle needed to sharpen specific teeth of a chain.
