Awhile back there was a post asking how to sharpen an auger blade. I needed to sharpen my blade after i drilled through the ice into the bottom. I have found a great tool for the job. The tool is called "Speedy Sharp". I was able to resharpen the blade to or better then the factory. It works on any blade. Go real slow and keep the blade contour. Three-10 swips and the blade should be sharp. Do both sides of the blade. Do not change the angle.
