Amatec (MH836r)

This black-line drawing of the simplex glyph for the personal name Amatec (“Paper Cutter”) is attested here as a man’s name. The glyph shows simply a white triangle in a frontal view. This intends the word for paper, amatl. Given that paper is typically shown as a rectangle, the hypotenuse of the triangle seems to be the cutting edge, referring to the -tec part of the name (from tecqui, cutter). But another glyph for Amatec does show a rectangular piece of paper.
