I finally got around to learning how to and then actually sharpening 4 auger bits I bought a while ago for my brace. One is one of those nice old Irwins and I got it deadly sharp - works great. Another one I was able to get working really well, too. However, the last two have their nickers/spurs worn down to nothing such that the horizontal cutting surface touches the wood first. I'm under the impression that these are junk? Do I just chuck them in the recycling or repurpose them in some more elegant way? Open to ideas!
