I have sharpened fusions. I have the G6 blades on our 160Z. Those blades have about 20 hours on them and I have sharpened them twice and they have a few nicks already. I don't know man they seemed to sharpen up about the same as the marbane blades.
Here is a small lawn from today. Cut at 4" with 35 hours on the oem blades unsharpened. These poor people have been with out power since friday.
