Earlier this summer I was using my SOG Flash II to open a bag of ice and somehow I rolled the edge for about 1/8" towards the back in the blade. My sharpmaker took the rolled steel off very quickly but then it formed a flat spot on the edge. I had the rest of the knife ridiculously sharp so I figured i'd not mess with it and it would sharpen itself out eventually. I've sharpened it 3-4 times since and there's still the flat spot from the roll where it will not take an edge. Will this indeed straighten itself out in time or is there something special I need to do to fix this?
