Although The Mongols used the same arrow making techniques as most other Nations and Kingdoms that developed and used arrows, the key to their success was in the shape of their arrow head. Made of bronze or iron, they featured an 8-winged tip. The tip was extremely sharp. The side-fins could be left dulled or sharpened. On average a typical shaft was 13 to 15 inches long. Either pattern would cause extreme pain and sure death if removed. Often dipped in poison (or fecal mater), seldom did a defender withstand a barrage from them. The Mongolian Tip did not change throughout it's history (9th through 14th Century).
