"Take your chain saw's chain from dull to sharp in as little as 3 seconds with the portable Oregon PowerSharp system. This lightweight bar-mount sharpener is small enough for arborists and farmers to take out in the field and sharpen on the job and gives homeowners the confidence to keep their chains in top condition. The PowerSharp system consists of a chain, a bar and a bar-mount sharpener. When the chain gets dulled, sharpening is as easy as putting the sharpener on the blade and pressing the tip of the sharpener into a solid surface for a few seconds, bringing the unique top-cutting cutters into contact with the sharpening stone. This sharpens the chain and resurfaces the stone, thanks to a diamond-coated dresser link. There's no better way to do your heavy limbing, storm cleanup or trimming jobs than with a sharp chain, and there's no better way to get a sharp chain than with PowerSharp. File Size in.
