This rim-blown flute is a simple open-ended tube (See diagram above). The blowing edges were flat and sharpened (Example). Rim-blown flutes are characterized by sound production; they require a specific embouchure. The player uses their trained lips to blow across the blowing edge to create a sound. Some makers call these flutes, "Anasazi" Flutes. I use the term "Pueblo Flutes", or more specifically, "Pueblo-style Rim-blown Flutes".
