Was there a recent post on the "Unicorn Edge" or some such?

Having looked at another forum to see what this was about, it was put on a back burner to give a try.

Finally had a plane blade to give it a try.

It did provide a very good edge able to make an incredibly thin shaving on a piece of pine.

Though there is a possibility this could be done in a way to be detrimental to the edge, like all sharpening that is a matter of the person being in control of things.

My question, was there ever an explanation of choosing "Unicorn Edge" as a name or was it just an obvious choice for the likelihood of ever seeing one?
