What you described misunderstands or at least poorly describes the problem. > Right, because which blade half is on the bottom affects which direction you need to apply force so the blades meet tightly. That would violate Newton's Third Law of motion, so no. You don't have to apply force in any different direction if you put scissors with symmetric handles in the wrong hand. You will, however, end up tilting the scis…

> You don't have to apply force in any different direction if you put scissors with symmetric handles in the wrong hand. [...] But that's not the same as needing to apply force any differently. For precision made scissors with tight tolerances at the pivot joint and sharp blades (premium brands like Kai, Gingher, etc), it will cut with either hand. But for scissors with a loose rivet (like cheaper scissors very commo…

And for the average scissors I use, it won't cut properly in either hand. Interestingly haircut scissors are better at cutting paper than regular paper scissors! I tried disassembling a pair of haircut scissors, and found the screw is interestingly rotationally locked to the blade next to the nut (rather than screw head), and the nut has a spring-loaded locking mechanism (a planar version of mouse wheel notches) so it doesn't rotate unless you turn the nut with a large amount of torque.

This is an incredible collection. Thank you so much for keeping it

I still want to write some software to support community-curated lists of related links. It would include whatever I'm currently posting as "related"* plus fabulous contributions like cloudier's above. * https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...

I've never really understood (said like I've spent much time thinking about it!) why wrong-handed scissors are so difficult/impossible to use. We must angle them slightly, sub-consciously, w.r.t. our standing vertical (out of the plane projected forward from our figure)?

I'm a lefty and left-handed scissors are impossible for me to use. And not from lack of exposure I think, one of my memories from elementary school was the teacher trying to make me use left-handed scissors because she knew I was a lefty, but they simply wouldn't cut for me.

I think there must be more to the left/right handed thing, because I'm effectively right-handed in everything I do except writing. Even in novel tasks I haven't done before: I'll try first left handed, it doesn't work, then I try again right handed and it works fine. But when it comes to writing specifically, I'm very clearly a lefty.

Lovely little collection of sites like this, which showed up last time - https://href.cool/Crimes/Simple (I linked to the category that the scissors is filed under, but the collection is extensive)

Ironically named site doesn't like deep linking -- navigate from https://href.cool/

Are you a lefty? I'm a lefty scissors user as well so I've gotten used to right hand scissors (you just push the bottom blade to the right as you cut). That may not be the case for most right handed folks since it "just works" most of the time.

I just gave up & learned scissors, guitar, fencing, etc right-handed. Only things I do as a lefty are writing and baseball.

That's the first time I've heard that there are left- and right-handed scissors. Is there actually a noticeable difference in usage?

oh yeah, I'm left handed and right handed scissors just don't cut anything when I use my left hand, they just fold the paper

I'm also left handed and the only difference I've ever noticed is that when I use scissors (whatever they may come from) with my right hand, the cuts are less precise. That's it. And everything I do with my right hand is less precise than when I do it with my left hand.

I just got the nearest pair of scissors and cut a sheet of paper with it, it was equally easy both with my left hand and my right. Even holding it very loosely so I couldn't secretly unconsciously apply some horizontal force it cut fine, as well as when tilted slightly left or right. The two halves seem perfectly identical, too, so I don't know what's this talk about "nearer blade on the bottom" either by some siblin…

I did the same and had the same result. From reading the the other comments, I suspect a high-end pair of scissors is more tolerant of technique whereas as low end scissor you have to push and pull the blades just so for it to work.

Some scissors are more ambidextrous than others. If the blades are curved towards each other enough then you may not need sideways pressure from your thumb and fingers, and even sideways pressure in the wrong direction may not matter. I have some scissors like this and some not.

Alternatively, it's possible to apply the sideways pressure in the opposite direction to the "natural" one, and thereby use scissors with the hand they're not intended for (you may even be doing that without realising - I do). My dad is left-handed but struggles to use left-handed scissors as he didn't have access to them until later in life and is just used to applying sideways pressure in the "wrong" direction.

I've never heard of nor seen scissors with blades curved towards each other and I don't see why they ever would be anything but straight in that dimension.
