Glad you weren't worse. You have been warned. Take heed.
To me the key is that you were tired. We should know when to quit. I was working one night, tired, and in a hurry to make one last cut. As the saw was slowing down for the change in setup, I saw my own had, as if it belonged to somebody else, reaching out to pinch the blade to stop it. I was stunned. Did not actually touch it. Turned the lights out and left. Not qualified at that moment.
Thanks again and don't work when tired.
