These are handforged arrow heads from the IV-VIII century from the eastern areas. Hun and Avar wariors used them against the Romains and other enemies. In the early times these heads were smaller (7-15 grams) but later appeared the bigger ones (15-50 grams). The two and three-bladed arrowheads are made by black-smithing work. It can be ordered from 7 to 50 grams. I follow the contemporary material of finds, so if you send me a picture of a historical arrowhead I can prepare it.
