I needed to cut some rags today out of old t-shirts, so I did some more testing

it was definitely noticeable with the cheap scissors in the wrong hand if not compensated for, and even aside from actual performance, I can clearly see the blades spread apart when closing with regular form in the off hand. with compensation to push the blades together, they cut fine, but yeah that would be annoying to have to do all the time

with the decent fiskars scissors though, no difference at all

I am surprised by how the paper and envelope cutting tests I did yesterday showed no difference, though. I guess the paper is rigid enough to hold the blades together before they actually cut or something, whereas the fabric clear tries to get between and spread them
