Well, I'm not Ed but I pretty much agree with your conclusion. If you miss the hardening you want with a blade then you need to try again. I don't know about repeated normalizations after a failed hardening because you didn't grow the grain on the previous quench unless you way over heated the blade preparing it for the quench. Depending on the alloy that you're working with, I would worry about over normalizing the blade and reducing the grain size too much and reducing hardenability. However, if that does occur, you can soak at a high temperature to increase the size of the grain and start the heat treatment over.
