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?
A version of what you are saying is called cross dominance. Where a person is “handed” but users different hands for different things. For example, I write right handed but play sports and shoot left handed. I use left handed scissors but right handed hammer, screwdriver. All of the things feel awkward with the wrong hand but that hand changes with the task.
It’s so hard to find left-handed hammers that I’m sure you just felt forced to do it the other way.
Life hack: Buy two hammers, and mark them with the letters L and R. This way you’ll know which is which.
