I also don't think "awesome lists" are a sufficient solution for a number of reasons. Like this list is a perfect example of something that would (1) definitely get ignored on GitHub, (2) not reach the most likely target audiences, (3) not be easy to contribute to for basically anyone who doesn't know what a "git" is (so, the majority of people on earth)
We'd be looking to make the minimum possible change while adding such a feature. The goal is a "splash free dive" as sctb used to say. Most ways that I've thought of doing it (so far) involve too much splash.

People talking about causing the paper to fold are either describing how they have subconsciously tilted the scissors to be able to see where they are cutting or the fact that many but not all scissors have handle shapes that curve wrong if held in the wrong hand so they end up holding those specific scissors oddly, which means that the scissors are no longer slicing perpendicular to the paper.
But handle curvature is not a requirement of scissors, just a characteristic of some of them.
If the scissors don't have ergonomically sloped handles, an ambidextrous person can comfortably cut with either hand if they don't look at what they're doing.
You probably do this without thinking about it due to practice, but if you watch little kids try to use scissors, they'll sometimes end up with the paper just turning sideways and folding flat between the blades.
If you use the correct handed scissors, your natural grasp will cause this to happen fairly easily. If you use the wrong handed scissors, you have to push your thumb away from your palm at the same time you bring it closer to your fingers. Unnatural and uncomfortable.
> 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 scissors to the side so that you can see what you're doing. But that's not the same as needing to apply force any differently. It's a required sight issue not a required force issue. Anything else only comes from handle shape.
If the scissors don't have ergonomically sloped handles, an ambidextrous person can comfortably cut with either hand if they don't look at what they're doing.
Have you watched little kids learn to use scissors? You really do need to apply force to bring the blades together or they won't cut well. You likely do this unconsciously. I didn't think about it until I was teaching my children how to cut with scissors and noticed that they would generally end up folding the paper were I could cut it (toddler scissors aren't very sharp, so it's even more important to push the blades together from the side).
It depends on the scissors. With the pair I'm holding right now, even if I'm actively pushing so the blades would move apart, they stay tight enough to cut fine.
Notably, the blades are curved into each other, which is capable of compensating for a moderate amount of hinge slack and narrowing the cutting to a single point. And the hinge has very little slack in the first place because it has a big flat mating surface.
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 common in kids' schools), the gp (ianferrel) you replied to is correct: the blades will not close tightly if the wrong hand is used to squeeze. The loose rivet scissors in the wrong hand will fold the paper instead of cutting it because the natural finger-closing motion will spread the blades apart creating a tiny gap instead of making them touch.
Here's a 1-minute video that tries to visually explain what a left-handed person struggling with a right-handed scissor experiences: https://www.youtube.com/watch?v=wyGCvSCnkWk
Scissor ergonomics aligns the handles so applying the finger-to-base-of-thumb grip to the handles (with the upper handle pressed against the outside of your thumb’s knuckle) pulls the blades together. In order to do that, scissors have to be designed to fit either a left or right hand.
To use scissors wrong handed you have to catch the outside of your finger knuckles against the lower handle and pinch the upper handle down with your thumb.
Yes! You do!
So scissors hinge on a pivot point, and they hinge in two dimensions. They mostly move in the dimension that they cut in, but they also move a little in the perpendicular dimension. And in order to bring the cutting edges closer, you move the handle ends farther away. If you're using the correct-handed scissors, doing so is easy and natural because your hand grip curls one way easily. If you then switch the same scissors to the other hand, it's hard and uncomfortable because your other hand is a mirror image and your natural hand grip curls to bring the handles closer and the cutting edges farther away.
The fact that you keep mentioning that this violates some law of physics is bonkers.
What makes you so sure? The ergonomics of the thumb, fingers, and hand are not symmetric. The left-handed people who struggled with right-handed scissors as kids suggest otherwise.
When holding scissors, the bottom blade is held fairly steady. The top blade tends to get pushed away from the rest of the hand by the action of the thumb. If the top blade is on the far side of the scissors (away from the hand), the far blade edge will get pushed towards the near blade edge when the thumb handle is pushed away (because the blade is on the other side of the hinge from the handle). If the top blade is on the near side of the scissors (the hand side), by pushing the thumb handle away from you, you are separating the two blades rather than pushing them together.
So on right handed scissors, with the thumb handle facing up, the thumb blade is on the left side of the hinge. That way the natural "push away" force from the thumb will keep the blades close together when held in the right hand. On left handed scissors, the thumb blade is on the right side of the hinge, for the correct push-together force when held in the left hand.

The only real benefit I've ever noticed of left handed scissors is that when you hold them in your left hand, you can see the point on the paper where the blades are going to cut. Holding a pair of right handed scissors in your left hand (or vice-versa) obscures that point behind the top blade, making it a lot harder to make accurate cuts.
If you try holding a pair of regular right handed scissor in your left hand you should be able to see the issue of the top blade covering the part of the paper you want to cut. Which let me tell you, makes following dotted lines a lot harder in school if you're using them on the wrong hand...
That's the only difference I've ever come across anyway, not sure what other commenters are talking about with the paper turning sideways!
Bread knifes have a ever so slight slant to the cutting surface, to ensure that it actually goes straight through the bread. Without it the bottom of the slice will be a little more narrow, or thicker, I can't remember. Anyway, if your left handed the cut goes into the bread at an angle and the bottom get much wider than the top. This happens because the slant in the knife is to the wrong side (for left handed people). It is basically impossible to compensate for, without attempting to use your right hand, which just makes it worse really.
The price of the cheapest available left handed bread knife I've been able to find: USD100.
Perfect slice!
You can use this technique even with blunt knives like butter knives.
I got a cutting knife (Øyo japansk kokkekniv), which has holes in it and a bump on one side to get rid of vacuum and things sticking to the knife when cutting. I actually got that in a lefty version, with the bumps on the other side.
The only time I've actually seen one in real life is at the left-handed store on the San Francisco wharf!
Anyway, if you've got recommendations I'd love to hear them.
So in short I have no idea what everyone's on about.
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.
When you use left handed scissors with your right hand, you apply some force to the blades that moves them slightly apart, while with right-handed ones, you force them together tightly. You need to actively work against that.
The only difference is which side of the visible blade the cut is.
You put a couple fingers through the bottom loop. Most people don't pull those straight upward, but pull a bit toward their hand. This pushes the blade to the left as it closes. Likewise with the thumb you push away a bit, which pushes the blade to the right. Thus, both blades are pushed against each other.
Sure, you could balance the scissors perfectly and only go straight up/down. But this won't work very well when cutting something difficult since there are no forces balancing each other out. It also won't work with looser scissors (every pair in elementary school) ad the blades will remain apart from each other.
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.
People tend to damage the left-handed scissors because they use them wrong: it bends the blades slightly apart. If you apply seemingly-excessive lateral force to the handles while closing the blades together, they work fine. (Also, new, undamaged pairs work fine.)
You do have to hold left-handed scissors at a slightly different angle to cut, though. If you're used to right-handed scissors, it's a difficult adjustment to make.
Funnily enough, you can also see well if you cut with right-handed scissors on your left side, but with the paper held above your eye-line.
I love these little measures of attention to detail. You can tell when a craftsman really thought about their work, vs. when a mere implementer stops once the design is shippable and the requirements are met. Similar to the "Cheese in the wrong place" controversy over the Google burger emoji[1].

I realize one option is supposed to be ludicrous, but based on this post, either option is possible.
(I linked to the category that the scissors is filed under, but the collection is extensive)
Most designers may be on iOS, but saying most users are on iOS is objectively not true, except in very niche apps.
It’s cargo cult.

It’s neat I guess, but isn’t really a productive pursuit.
Yes, and? No one claimed otherwise. It's just a fun thing someone did, shared with other people who might want to be briefly entertained.
The article say it.
> but isn’t really a productive pursuit.
It's fun and kinda interesting though. If you reflect on what productive things enable, at the end, it's always "futile".
Heaven forbid someone's curiosity doesn't result in something useful.
Sometimes people do things for fun and self-satisfaction.
> Unlike the real world tool it represents, the emoji’s job is to convey the idea, especially at small sizes. It doesn’t need to be able to swing or cut things. Nevertheless, let’s judge them on that irrelevant criterion.
