Can People Be Neither Right Nor Left Handed?

And just to pull this OT discussion back to OP relevance, has anybody ever done a study on the handedness of octopi? That would be fascinating, IMO... Still 80/20 do you think?

Interesting, thanks!

Unlike in humans, this handedness is split more or less 50-50, rather than being biased towards right-handers. But it does seem to show why the many-limbed creatures go to the trouble of choosing a favourite.

...using the NumPad should be easier for right-handed people. But spacebar? Right or left thumb - even I as a pretty much right handed person do it both ways. Where's the difficulty / difference?

I would rather have it on the left side of the keyboard, even if I am right handed.

Inspect carefully, it turns out there are two versions of left handed scissors.

Right handed scissors are assembled with the blade that is on top of the work positioned to the right during use. That allows you do see exactly where you are cutting.

Some left handed scissors just change the handles for a more comfortable fit without changing the blade overlap. This positions the top blade to block your view of the cut line.

I hear that is rather annoying for lefties.

If I use right handed scissors in my left had, they do not cut.
Something to do with keeping the blades tight against one another.
the left hand pushes them apart a little bit.

I am right handed. I play guitar right handed but I play drums left handed. Trying to do either vice versa results in a sonic mess or personal body damage.

I don't get these left/tight handed references to sports or instruments.

Is the 'better' hand to be the upper or lower grip on a bat, or rather the left or right side of the pitcher when the batter steps up to the plate, or on which 'side' of the rink the hockey player is on when looking from his own goal.
Should the 'better' hand be strumming or playing the chords.
These are would just consider conventions that have developed and continued on.

Holding a tennis racket, or kicking a field goal - that makes sense.

Knitting - maybe that is a left or right handed activity, but no one talks about that.
( By the way I haven't knitted since grade 3 when we made those rope things from thread and a old spool. )
Knitters UNITE - are you a left or right handed knitter.

No it is not convention. Have you never played squash, tennis or badminton?
Never held a guitar?
One way feels 'wrong' and the other way feels natural.
As wrong and as natural as writing with your right or left.

One handed actions - definitely a handedness to them.
Batting - convention as both hands are used - where does it say the left or right hand should be above the other on the bat? In fact, a left handed batter has his right eye closer to the pitch, so he should really be a right eye handed batter.

I bat right handed, but play hockey left handed, and both feel natural, but where is the logic in naming one stance over the other.

Ok I get you now. Yes that is convention. How did the nomenclature arise?
My guess is a bunch of guys are doing something right handed because that is the norm. One guy is doing it different because he is left handed so that is the left handed position.
No one says Jan Ackerman is right handed he just plays.
EVERYONE noticed Jimi was a leftie, it looks odd.

An example. I went to drum clinic for schools when I was about 14. I was the only leftie for a snare session of about 10 or so kids and I was outed.
I was quite embarrassed because he said I should learn to right handed and would be an inconvenience in an orchestra. How would that work if I was the only leftie violinist?
I actually tried it and it felt awful so I switched back and put my foot down. I am playing left and my teacher who was a jazz drummer thought I played well.
So, the right way and the wrong way! The odd way is left by default because of the numbers.
