Pultruded is a word that describes the manufacturing process. When carbon arrows first came out, they were all small diameter and were manufactured by pulling epoxy coated glass fibers through a die. The nock and point connection points were called “outserts” as the shafts were so small they had to go on the outside of the shaft.
The first carbon arrow shafts were actually re-purposed shafts originally manufactured for tents and kites in France. Once their popularity increased, shafts were manufactured for the purpose of making arrows.
Then the larger shafts were “invented” and manufactured by weaving or laying the glass fibers around a spindle. The larger diameter shafts were thought to be nicer because they looked more like arrows and had internal components.
Now we are back to reinventing the smaller diameter shafts again, only this time with small nock and point inserts that go on the inside.
I don’t mean to disparage arrows of any sort. I’m sorry if I came across that way.
