Ruler trick ()

...one, chase the wear out with the ruler trick and a half mm stainless rule and the back bevel grew trying to meet the microscope "all wear removed" standard. One of the reasons that test was a pain was that each iteration, I would have to do the ruler trick on the edges twice to remove all vertical lines from planing wood (vertical meaning in the direction of iron length).

The other option would be to do the ruler trick and keep the wear bevel the same size and ignore the insignificant wear left at the edge And that option would've been fine - the wear scratches are less significant than most sharpening stone scratches.

In the clearance wars, the assertion was that this doesn't happen or it's uncontrollable. The answer is somewhere in the middle. I never had an issue removing functional wear from a bu plane with 30 seconds or so on a slurried 8k stone. But when the long back wear was pointed out and then I wanted to remove all cosmetic scratches of any kind all the way into the back, then that took a lot more work. The important part of it being that the few deep scratches that leave spider webbing don't need to be removed each time as they weren't noticeable when using the plane (none deep enough to split shavings).

If an iron is taken to dullness (complete lack of clearance), though, and the ruler trick is used on a bevel down plane with a cap iron, it's not true that with a 0.5mm rule that it can be used to remove all wear without growing. I didn't try other rules and probably wouldn't have ever even thought that keeping it the same size didn't suffice in removing all everything (which means that what's left behind may not be that significant).

applied pressure at the tip on a faster stone is a lot more practical than the ruler trick, though. And faster.
