I don't have any hedges at the moment but will probably soon. Not that it will be a big deal for me, the amount I'd use a hedge trimmer would be minimal and would go for the manual type or electric over gas powered. But here's my question about electric/gas trimmers - how do you go about sharpening them? Is there a special easy way to do it? I recently separated the blades on one, and hand filed all three sides of each cutter on a 30" setup. It took a ridiculous amount of time, wasn't easy, and left me with a feeling of carpal tunnel syndrome. Is there a special tool or jog for it? How can a local guy charge $22 to do it?
