I generally agree, with some nitpicks.

The old canon several times mentions that wielding a lightsaber is actually extremely difficult and unintuitive...

...because the 'blade' is literally weightless, that alone would throw off a lot of wielders of more conventional swords...

... but also because the saber, potentially as a byproduct of the 'coherence field,'... produces strong, unituitive gryoscopic forces when moved or rotated at various angles and speeds.

...

The old explanation I remember is roughly that force sensitives essentially just intuitively know how to counteract this, to varying degrees of proficiency, but a non force sensitive, a non force user... they'd pick it up and awkwardly flail about with it as it seemingly gains and loses weight, is being pushed and pulled in crazy directions that make no sense compared to just, a physical sword or staff.

Sort of like trying to use a very, very poorly balanced real world melee weapon, but the weapon's poor balance also actively changes, like its center of gravity just seemingly randomly alters as you move it.

Basically, a non force user fights the weapon, whereas a skilled force user understands it, and in a more physically tangible sense, literally allows the weapon to guide their combat movements and style, they know when to go 'with' it and when to go 'against' it, to achieve the actual desired motion.

This is kind of sort of depicted in the Mandalorian, with the Darksaber seemingly becoming exhaustively heavy, massive, and Mando has to... learn how to use it, how to work with it.

And also: yes, Han uses a lightsaber in the OT, but most of the early expanded universe did just explain that by saying he is actually force sensitive, that his absurd luck and piloting skill in various situations does mean he is actually a untrained force user, he just also is a stubborn ass who thinks the Force is bullshit, at least initially, lol.

...

But anyway, yes, they used to make lightsabers out of a wider variety of crystals, not just 'kyber'... and yes, i also do remember many different variants of how 'kyber' was actually spelled.

For the life of me I thought its proper spelling was 'khyber' until i bothered to look it up in an actual wiki in the last couple of months.

That could be me misremembering, or maybe that was what I originally read decades ago now, or maybe what i am rembering got 'telephoned' through a bunch of people first, on some forum.

....Man now I kinda want to set up SWGEmu, hahahah!
