Re: in plane iron testing, I found two options..

David, as you know i do not use the Ruler Trick. But some will swear by it .. as no doubt some swear at it :)

Many years ago I, when I was using BU planes as my primary choice, there was a heated discussion on this forum (for a change :) ) about the wear bevel. I recall mentioning to Larry that I did not experience the effects, and probably because I stropped the back of the blade on leather.

One might suggest doing the same with a buff. I am not sure that the results would be equivalent. A leather strop will create a more predictable result.

The variability of the buffing angles (in the absence of checking with a microscope, which is the situation for most users) is what I am missing with the unicorn buffing in preparing BU plane blades. There is a very real difference in performance on interlocked grain when a BU plane is cutting at 55- and 62 degrees. I described this earlier: very thin shavings and straight grain will not reveal how well you are faring with BU blades. You really need to be testing this out on interlocked grain, and using your standard thickness shavings.

In my mind this is a lot like learning to set up the chipbreaker. Trial-and-error gets you closer to the ideal distance/angle. No doubt that we will look back in the months to come and wonder why it was so difficult back then.
