Thsnk you, Gentlemen!
Those were splendid aproaches to the subject.
I just wonder why this guy i visited the other day, who sells and collects weapons for a few decades, immediately catalogued it as a weapon ... actually a rural crude pike head. But of course the guy could be wrong and i am not going to act as if he were my local weapons guru ... enough of that fashion for the time being
In view of all that has been said and, pleasing Greeks and Trojans, i will provisionaly call it
artitoolweaponfact ... or
arteferramentarmafacto in portuguese
... if you allow me for the humour.
There is still one source i didn't yet consult, as it's a bit far from here and i only go there every now and then. He does not only know about ancient and old weapons, but also the most varied early ages artifacts. If this kind of things was ever seen around before, there is a great chance he is the one who saw them.
Untill then, all kinds of hints will be most wellcome.
