A type  shown most often in the Spanish Codices.  This replica showcases one of the most unique weapons known from Mesoamerica, the Macuahuitl, or Obsidian war club. This weapon had its origin in Pre-Columbian Meso-America, and was at its height of use during the Spanish conquest of the 1500's.  There are only a few surviving fragments known, but during this time of Conquest the Spanish drew many descriptions which are available for study today.  This and other types are seen in the Codex Mendoza, the Codice Tudela and the Codex Ixtlilxochitl in the Bibliotheque Nationale in Paris, France.
This model is 24 inches long, as most of the club types shown are depicted around arm length. The main club or paddle is made in a curled Cherry wood, and is grooved to fit the glued in Obsidian flakes. There are several styles that can be found depicted in the descriptions, and many of these are made from long thin Obsidian blades made from prepared cores.  Other types were made with larger bifaced squares, and that is what is seen most in the club category.  This is the type that is modeled here, with small bifaces that are pressure flaked to square shape. They are sharp the way that arrowheads are when pressure flaked, rather than raw flake surgical scalpel level sharp on raw core blades. This is the model seen most often in the Spanish Codex drawings.  These obsidian pieces were made in the traditional manner, hand knapped from prepared real obsidian blade cores.  The art pictures above show drawings in the Spanish Codices for correct scale of size and manner of wielding.
