A trick I recently discovered: Sharpening a chainsaw with an angle grinder works really well!

Com: micheal: I don´t know, where is problem.

When you have older chain, no time and no chain-grinder,

this is fastest way and If you have precise movements of your hands, you can make it really good.

I´m sharpening my chain same way and it cuts really straight and well.

And the chain cant split and hit you to your face because of sharpening this way - you are sharpening teeth, no cutting the chain links
