I don’t mean Ambidextrous!
Yesterday I tried cutting a vegetable with the knife in my non-dominant hand and it was a weird and uncomfortable thing. I wonder if there are people who have that distinct discomfort of using your “bad” hand, but on both hands?
I don’t think it would fall under ambidexterity, because that kinda implies someone is comfortable with either hand, but could someone be uncomfortable with both?
This practice was not exclusively Soviet. It happened in the rest of Europe too, even long before the Soviet Union, pupils were tought to use their fine hand, i.e. their right, for writing, while their left was bound to their chair.
However, as being left handed isn’t exclusively a matter training, this practice causes drawbacks in other fields.
One of my teachers was re-educated that way, from left handed to right handed and he hated it. But he could write mirrored with his left hand perfectly, which was an amazing feat. Sometimes he would write on the chalk board with both hands, the same word but mirrored, that was pretty cool.
