The Roman object was used to measure the size of the diameter of the spear for the tip. Since not all spears were identical, this item was used to determine the diameter of the spear cone. Because you need a standardization system for the army so that both in the east and in the west the soldiers have the same spears. The tip of the spear was inserted into this object and the carpenter or blacksmith understood what needed to be improved in the spear so that one was similar to the rest and so that the tip could be put on it.
There are many through holes in the object, each of which corresponds to its own diameter of the spear.
