I’ve blogged in the past about sharpening chainsaws. At its most basic, that means using a round file on the saw chain’s cutters and a flat file on the guides. Various power sharpeners are also available. All take time, and most require removing the saw chain from the bar. Now, thereâ€™s a better way.
The Oregon PowerSharp lets you work until the chain dulls and then sharpens the saw chain in secondsâ€”on the bar. You’re back cutting in less time than it takes to add fuel. The PowerSharp system consists of a specially designed saw chain with top sharpening links, a guide bar and a bar mount sharpener with a replaceable sharpening stone. The chain also includes special diamond-coated dresser links that resurface the stone.
This past week, I tried out the system. After clearing several hundred feet of brush choked fence line (at dirt level), the saw chain was still sharp. Finally, I resorted to the unthinkable. I revved up the motor and ran the saw chain across a rock. Sparks flew. When I did my next cut on a log, I had to practically push it through.
I stopped the chainsaw and latched the sharpener to the end of the bar. I then restarted the motor and pushed the foot of the sharpener into the log for about five seconds. Again sparks flew, this time as the saw chain sharpened.Â
When I attacked the log again, the saw pulled itself through in a third the time, a sure sign of a sharp saw chain. If you have a chainsaw, I recommend checking out PowerSharp. Systems are available in 14, 16 and 18-inich bars, depending on brand. At $75 to $80 for a system, it’s a steal.
