I'm posting this to highlight what I think is a terrific practice by a manufacturer, WoodJoy. Without further ado, here's the back of the blade from their Master spokeshave, which is a low-angle/bevel-up tool:

The part that I really like is that the back is hollow-ground, such that it can be easily flattened and polished. Low-angle shaves have very minimal clearance, so "ruler-tricking" isn't an option. You typically have to polish the blade flat, as with the Veritas blade of which I posted a picture in the ruler trick thread. WoodJoy also hollow-grinds their blade faces, which makes first-time tuning a snap.
Traditionalists are out of luck, though: These irons are cryo A2.
I promise, this is the last of the "blade porn".
