Has anyone ever done this? I just ordered a new set of these stealth stx ripper blades for my model 79 8 inch auger, and I got the complete set of big ripper and two point rippers. I see on the jiffy site some instructions to sharpen them. As I have never been able to sharpen anything without making it more dull than when I started, I was hoping to send these in to Jiffy to sharpen them, but it doesn't look like they do this. Does anyone know where there might be a place to send in the used ones once the new ones come in and have them sharpened?
