I don't think there will be a winner on this one ... but let me try .
.
This ethno device is not a weapon, but it surely has a martial look, with its 1,650 Kgs. and 46 cms. length ... and capable to drill a 7 cms. hole.
But for drilling what ? I was told this is a tool associated with well sweep making; like for drilling a hole in the pole, i don't know
In any case the blacksmith has to be a rather skilled artisan, to make such an object to be effective.
Any ideas ?
