tecpatl (Mdz16r)
This symplex glyph of a flint knife (tecpatl)] also stands for the place name Tecpatlan. It is vertical and divided with a diagonal line. Above the divide, the knife is painted red, and below it, the knife is white. Instead of having a point at the bottom, it has a squared-off section.
