Yeah, I'm sure it isn't on upside down. The grinder is very high speed and I have a feeling it tightened up beyond the wratchet actions capability to loosen it. I understand your issue about finding the key when you need it, but I have mine taped lengthwise on the end of the cord, so I always unplug it before chainging blades; I do this with all similar power tools, just a good habit from back in my apprentice days and I still have all of my fingers.
