Doesn't it? I thought a scandi had to have a wide flat stone on a flat surface. That's basically the whole point of my question. About the rest of your post I won't bother commenting.

Just sharpen it like any other knife. Then you end up with a more convexed grind.
If you insist on maintaining a perfect scandi grind, in this SHTF scenario, then you are focusing on the wrong thing.
