Yes, I know what you are talking about. I have one, on one of my rulers but I bought it at a quilt show in OR about 9 years ago and there is not a marking on it. I always planned on getting another for my other long ruler but have not seen them. Good luck finding one. I too worry about cutting myself. You are probably saving a few of us getting cut. Guess I should buy the glove. Good luck, it has to hurt and I am a nurse who does not like pain.
