It’s not the view obscuring that’s really the problem, though it is a side effect. It’s the pressure exerted while squeezing that only works for the correct hand in scissors.

If you can figure out how to contort your fingers to squeeze the blades together enough, you can use the wrong scissors, but I just learned how to cut righty because I could never find good lefty scissors as a kid. Same reason I used the mouse righty.

By the way: The view of the line is going to be obscured cutting curves in the direction of the cutting hand no matter the side.

It's all I've ever complained about. Never noticed the blade thing, but I understand what you mean.

You're not wrong, and the ways around it are awkward, but they exist. Personally, I'll often flip the point towards the wrist of the hand holding it and cut from the opposite side of my body, but I'm basically ambi-dextrous anyways.
