How come nobody sharpens the metal to turn into blades and spears?

I was thinking about it today, but, if you were stuck in Fromville, wouldn’t you want to take all the metal that you could get and try to make a smelter and sharpening area, and grind it up into some sharpened blades and swords and throwing stars that you could use against the creatures?

I mean, even if you only use them in traps, or something cool like a remote guillotine to cut off the head of one of the monsters just to see what happens, wouldn’t you use some of that random metal just sitting around sharpen it into weapons?
