also, there are quite a few materials that are beyond the ability of regular anglegrinders to cut, but they are prohibitively costly

Clickbait headline really, wouldn't mind some to play with though.

A (large bubble size) electric guitar body would look awesome.

And from the text, once it is inside the metal - that's when it blunts the blade. So it seems to be soft under pressure, so probably wouldn't be able to saw. It's most likely flop apart.
For a lock, how thick would it have to be to protect the lock mechanism? Would you actually benefit weight-wise?

I doubt we’ll see it used in locks because it’s really, really expensive to make.
More likely it’ll be used for armour; foamed metals without ceramics are already pretty good against bullets.
