Hi there, I used to have an Eskymo and and I used a honing stone. It worked great as long as you covered the whole radius. You can get em razor sharp this way with a little spit and elbow grease. I tried using a grinding wheel but could not hold the correct cutting angle. Eskymo new what they were doing when they put a radius on those blades making it nearly impossible for someone without a cnc to sharpen them in mass numbers forcing guys to buy new ones!
