In the end, as far as adding a sword to my collection, it doesn't matter what I call this hamon or that one. I can check my reference books for that. I don't buy a sword because it is notare or suguha or whatever. I buy it because I appreciate the art and history of it and the craftsmanship that went into styling that hamon, as well as the other aspects of the blade.
That being said, I do envy my friends like Ray who are walking reference books themselves...
