Why do the Agave Blanks have no Stringer?

The blanks do not have a stringer but a middle pole that shapers can use as a guide. Here you simply mark half of the middle stem and can be sure to have the center. Why the Agave blanks don't have a stringer is because they don't need it due to their fiber structure. You can imagine that the entire blank consists of many stringers. The only difference is that they are holistic, like a lot of straws close together. This makes them incredibly light, but also very stable.
