During use a chainsaw chain can loose its sharp edge and become dull or blunt. This will affect performance and if not put right the chain can heat up causing unnecessary wear and tear. There are a number of options available to chainsaw users to allow simple and effective chain sharpening on site. There is the 12v sure sharp which runs from a 12v cigarette lighter plug. There is also the precision filing guide which can be easily attached to the bar and used on site. And the handiest tool of all, the filing clamp for holding the saw steady.
All these tools can help increase the life of your chain and bar. For a full demonstration of how to sharpen a chain please view our "how to sharpen a chain" video
