A macuahuitl ([maːˈkʷawit͡ɬ]) is a weapon, a wooden sword with several embedded obsidian blades. The name is derived from the Nahuatl language and means "hand-wood". [ 2 ] Its sides are embedded with prismatic blades traditionally made from obsidian , which is capable of producing an edge sharper than high quality steel razor blades.
They were cemented in place with bitumen or plant resin as an adhesive. This made the tepoztopilli vaguely similar to the macuahuitl or "macana", however it had a much smaller cutting edge and a longer handle. The greater length gave the weapon a superior reach, allowing the user to stand behind a line of more experienced warriors and then ...
The earliest meaning attributed to macana is a sword-like weapon made out of wood, but still sharp enough to be dangerous. [2] The term is also sometimes applied to the similar Aztec weapon, which is studded with pieces of obsidian in order to create a blade, though some authorities distinguish this item by using the Nahuatl name macuahuitl.
This is a list of historical pre-modern weapons grouped according to their uses, with rough classes set aside for very similar weapons. Some weapons may fit more than one category (e.g. the spear may be used either as a polearm or as a projectile), and the earliest gunpowder weapons which fit within the period are also included.

Antarctopelta, based on phylogenetic bracketing and known material, probably had a macuahuitl like its relative Stegouros. This structure was made up of several fused, flat osteoderms that occupied the end of the tail. Inside much of the macuahuitl there are no vertebrae, creating a largely fleshy space.
The terms bitumen and pyrobitumen have related definitions in the Earth's crust and in the laboratory. In geology, bitumen is the product of deposition and maturation of organic matter. The extractable organic material (EOM) in petroleum source rocks and reservoir rocks is defined as bitumen.
