This 'replica' costs 60 E, is probably from stainless steel, we can rather safely assume that it doesn't have any authenticity to speak of.
Mostly some kind of sword that holds shape similar to the 'falcata'.
But how do you know they're heavy?? That shop doesn't leave any data...and apparently bulky these weapons were made. Is there a special reason to make the blades this heavy in some swords while most examples of original are actually considerably more slender
But it's probably heavy indeed, overbuilt like most cheap reconstructions today.
I seriously doubt that anyone would ever make a sword out of pig iron, it's just doesn't have sense.... It's base product to make actual steel, and apparently wasn't even well known and used in Europe trough most of the medieval.I think making a thin, light sword that's both tough and sharp is more expensive and difficult than just sharpening up a chunk of pig iron.
