Just did some rough estimations and calculated the weight. Ofc I cant know its thinkness and e.g. if you take 2 or 4 cm, it doubles. I estimate around 80 kg, which can be lifted by a strong human, but obviously you cant keep the balance if you stretch your arm out and point the sword at someone. It will just fall to the ground at this point. (lever arm)
I actually wonder, if some strongman competitions with a medieval theme had some "Guts" events, where they tried out what could be achieved.
YT channels of former WSM like Brian Shaw and Eddie Hall are quite popular nowadays, it would be interesting to see them do something like that.
