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

1.35K 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?

When you open a right-handed scissors the left blade goes down and the right blade goes up.

The blades are in different positions depending on if it’s left or right handed.

General, the natural motion of your hand works in a very specific way. Scissors are engineered to work in conjunction with those motions to force the cutting edges together.

If you can visualize how the blades work together you can learn to force your left hand make them work

All my children are left-handed, I taught them to naturally use “handed” tools with their right hand as they were developing each skill. As they got older they learned to be ambidextrous with many of those things
