How do scissors “know” what hand you’re holding them in?

1.38K views

I’m left-handed and growing up, in school, there were never enough left handed scissors between myself and the maybe two other lefties in my class so I would often need to use right-handed scissors. But they would either not cut paper at all or kind of tear the paper, forcing me to switch to my right hand to get the scissors to cut smoothly.

Just yesterday I needed to trim a label and no matter how I angled the scissors, they would not cut the paper but they immediately did once I switched to my right hand. Thus, how do scissors “know” which hand you’re holding them in?

Scissors don’t actually “know” which hand you’re holding them in. However, most scissors have a design that favors the right hand. The blades are angled and shaped in a way that allows the cutting edge to cleanly slice through paper or other materials when held in the right hand. When held in the left hand, the blades can become misaligned and not cut properly, leading to the tearing or crumpling of the material being cut.

Some scissors are specifically designed for left-handed users with reversed blades and handles, but they are not as common as right-handed scissors. So, when using scissors in your non-dominant hand, it may take some practice and adjustments to get them to cut properly.
