The anvil, can make a lot of stuff with it. You can even use it to make fire, striking a piece of iron until it’s hot enough to light a forge or small fire. Older copies of the Machinery’s handbook(the machinist’s Bible) have a few things on blacksmithing.
I think the “bulletproof” claims are vastly over hyped. It can block 9mm and that’s about it. Rifle rounds can easily penetrate it lol.
