Perhaps the best known ancient Aztec weapon is the maquahuitl (macahuitl). This is sometimes compared to the sword, and it was a powerful, close contact weapon. Like the European sword, they came in two varieties - one handed and two handed. Made from wood (usually oak), they were about 3-4" wide and 3-4’ long. The two handed versions might be slightly wider and as tall as a person. Embedded in the edges was obsidian (volcanic stone) or flint.
The maquahuitls were incredibly strong, and the Spanish claimed they could chop the head off a horse with one blow. They were sharp and the Aztecs knew how to use them. They could not thrust like a sword, and so they lent themselves to a different type of warfare.
What about non metal weapons like the maquahuitl or the shark tooth sword?
