Making this suggestion to commemorate getting unique and generous event reward of whole 5 katanas.
Running around with both hands above the head often blocks the view.
Euro sabers are much better in this regard with their one-handed charge animation.
katana is not one hand but more a hand and a half that is can be 1 handed but is most effective with two, also is slashing weapon so one hand thrusts would almost be as week as one handed slashes
I only practiced using knives, not swords or sabers, however it seems obvious to me that an edged weapon that relies on powerful slashes is unideal for one handed use.
no stabing swords rapiers epees. cutlasses, falsion, katanas two handed. See knife attacks in real life reports slashes are often shallow death caused by exsanguination (blood loss) lethal one handed daggers like stilettos are stabbing to pierce organs. Sorry but try to bat one handed (yes powerful for a dagger only because you lack the hilt for two hands🤣). 1 with daggers one handed is a huge reach advantage, 36 to 44 is a far mor minor edge. 2 daggers a one hand hold is much faster, swords one hand is to cutting brush as two is to chopping down a tree so katana two hands
Get a cheap pressed metal replica katana and hold it one hand and then two, and tell me which you prefer.
In my handling of cheap pressed metal replica katana; I find that the balance is such that it doesn’t feel right holding it in one hand. Much less so trying to actually swing with the thing.
