The Macquuahuatl, or the Olman sword, was a flat wooden club with sharpened obsidian blades inserted into grooves along the side and affixed with a pine pitch adhesive from pine pitch, charcoal and rabbit droppings. The Olman Sword ranges from about four feet to almost six, the weapon came in one and two-handed variaties although in some rare cases ogres have been known to weild them with freightening brutality.
The macquuahuatl was wielded like a sword, although its cutting action was more like a saw. The weapon can sever heads, and there is at least one account of the maquahuitl beheading a horse. The flat wooden sides of the weapon could be used to bludgeon opponents, usually so as to avoid killing them so that they could be captured and sacrificed.
Obsidian can be sharpened to a finer edge than even highest quality steel; however, it quickly becomes dull with use and the obsidian needs to be regularly replaced. It also takes more time to swing the maquahuitl than a similar-sized sword, as well as more space, forcing Olman warriors to advance in loose formations.
