tecpatl (Mdz13r)
This element for a flint knife or obsidian blade (tecpatl) has been carved from the compound sign for the place name, Tecpatepec. In this example, we see three flint knives. They are red at the top and white at the bottom. A diagonal line divides the colors on each knife. The points that would appear at the lower end of the knives, which would have given them the marquise shape, are not visible; they were possibly meant to be buried in the top of the hill in the original compound glyph.

The red color may serve as a symbolic representation of blood, given that these knives could be used in sacrificial offerings. The reasons for giving three knives here is unknown as yet, but flint knives are found in both the tonalpohualli and xiuhpohualli calendars, which testifies to their religious significance.
