[TheForge] First 'Non-Cuttable' Material in the World: Proteus Could Upgrade Bike Locks, Armor

[Bruce]

I think the young'uns haven't are busy on other platforms and don't "do"
theforge.

That material is interesting, but could be defeated with a hot enough
torch.  The aluminum matrix would crumble if heated and then struck.
They'd do better with a malleable steel with embedded hard granules.  I
wouldn't know offhand how to achieve such a structure, but would consider
corundum microspheres in steel.  I don't know whether steel would "wet" the
corundum, however.
