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

1.34K 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 only cut correctly if the blades are pressing against each other. When you hold right-handed scissors in your right hand, the way that is natural and comfortable, you are pushing the blades together. When you put them in your left hand, you’re pushing them apart. Left-handed scissors have the blades switched (in addition to the handle looking different on the scissors that have differently sized loops for your thumb and rest of the fingers).

You can use scissors in the other hand they were designed for, by consciously applying the opposite force you normally would and pushing the blades together. But it’s a little uncomfortable.

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

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.

They don’t. Your hands go in opposite directions. The scissors have to, as well. Scissors, can-openers, spiral notebooks. A left-handed person writing in a standard notebook is going to be uncomfortable while their hand keeps hitting the spiral rings. Since English goes left to right, they’ll also have to deal with potentially smearing the letters and their skin getting stained. A right-handed person doesn’t have those problems because, as they write, they’re going away from the ink rather than over it.
