Terrestrial or extraterrestrial? 2 Photos attached

Any guesses, since photo was taken an edge has been sanded and polished to almost mirror shine. Highly magnetic, feels heavy. It almost looks like it has thumbprints.

So I assume it's solid iron? Steel? Slag? Meteorite?

It has sharp edges on some areas. Meteorites don't have sharp edges. Do a window test on it or an acid test perhaps both.

I did some research, and I have noticed a lot of meteorite specimens with sharp edges, although generally they do not have sharp edges.

What kind of acid test do you recommend? I have noticed there are a couple different ways.

Iron/Nickel acid test. You can buy it at a drug store like CVS I think. Yes, some iron meteorites do have sharp edges.
