Iron doesn't sharpen iron. What a dummy. Only a harder substance will sharpen a softer substance.
You underestimate what can be achieved by pounding and grinding.
Grinding, using a stone, which is harder than iron. They don't make sharpening stones from iron.
I don't know if this was to point out that a file is iron and that can sharpen stuff, but I'd like to point out that files are generally made from a tool steel alloy that is formulated to be quite a bit harder than iron/standard steels after it gets properly heat treated. Files aren't just "iron" and there's a lot of different steels that do different things.
Exclusively iron files are a thing, they just didn't make for as good a screencap, cuz they look like pressed turds. The point was only that stone isn't the only option for grinding. An iron file used on some other iron surface would smooth out the scaling on the file pretty quick; but it'd also do a bit of actual grinding on that surface as well.
So, it'd take a lot of grinding, most likely with many file, but you could 100% sharpen an iron edge with an iron file. ...and tbh, lots of grinding with many tools fits the theme the thread perfectly!
T12 carbon tool steel is more than just iron
I mean, -that- file is more than just iron, but it's also more recognizable as a file. Exclusively iron files are a thing; they just look like rectangular turds.
You can sharpen a knife with a chakmak, but I think it's made of a very hard steel.
