I thought katanas are made with shat metal, hence why they need to be folded so many times when they're being forged.

By no means an expert on the topic, but from what I do know you're both correct.
The iron used in Japanese steel making came from iron sands, which is super shitty and full of impurities. The process of turning it into steel was enormously labor intensive, not to mention expensive. So the majority of cheaper swords were indeed absolute crap. The Japanese didn't have the means to melt steel, so folding was a method of evening out/working out the impurities. Eventually you'd get to a high quality piece of steel.
That being said, Japanese swords and European style swords are entirely different beasts. Katanas and the like are much thinner blades - lighter, more agile, and designed for solely for slicing. Medieval European swords were much more solid, heavy duty swords designed for multiple deathly applications. If a thin Katana and a European longsword were to make full force contact, the Katana would get wrecked by virtue of the design differences.
