I have an Oregon Power Blade on my chainsaw. It has the extra holes in the blade you you can use their chainsaw sharpener. You can buy them as a set, and extra stones as you need them. You attach it to the blade then point it and rest it on the ground. Pull the trigger and press down for 3 to 5 seconds and it sharpens the chain.
Video of it on YouTube....
