Lightsaber

'Lightsabers are one of the most iconic weapons in all sci-fi, energy swords used by the Jedi and the Sith. Your basic lightsaber is a cylinder about 20cm long which at the push of a button emits a "blade" of plasma about a meter long which can reflect blaster fire and cut through pretty much everything that's not another lightsaber blade with minimal resistance.

Basic fluff

Non force users can user Lightsabers, but generally can't make the best of them.

Issues with Lightsabers

Specifically, weightless blades. Because light weighs pretty much as low a mass as you can get not counting your dick (oh snap!), the center of balance of the blade is likely somewhere near the end of the blade (going by that's where the battery is, and that they likely weigh more than the blade projector). The problem with this is that you are essentially wielding a lever which will, upon being hit, flop all over the place because your hands function as a hinge. This might be less the case when used in two hands but when used in one your sword will go all over the place when it is struck. There is some in-story stuff to justify this, mostly based around how the arc-waves that form the blade do have a kind of mass that balances it correctly, but this is mostly hand-waving the issues.

Another point is the double lightsaber. Based on a variety of unbladed pole-arms like the Gun or the Bo, it has a double-sized handle with the laser parts coming out from both ends. The problem with this style is that it gives the wielder only a limited surface to work with without burning their hands off. Maybe this can be discredited as training in the Force and all that jazz (plus, Ray Park is REALLY good at what he does), but this would still involve swinging a large dangerous rave stick very close to your body, and a good number of these styles involve holding the weapon near the end to gain great striking power at the tip of the weapon like with a pole-arm. With a lightsaber this is not possible, though not needed since it can just cut through anything by touching a target and letting the plasma do all the work.

And the lightwhip and all other kinds of outlandish lightsabers can go right fuck themselves. And don't use the Force argument, if someone focuses on holding a plasma whip properly they will get shot because, super powerful or not, you still have to think. The "lightcrossguard" on the lightsaber of Kylo Ren certainly looked silly, but for one: they gave him an edge in close combat letting him use them to burn his opponent in a bind, and secondly expanded material say they are vents required because his lightsaber is unstable. You'd think that his boss might fix that problem for him, but that would be using logic.

One of the biggest issues with lightsabers is shown in the side material of Star Wars itself. They block most energy blots well enough. Assassins who specialize in killing Jedi use slug throwers to bypass their ability to block blaster bolts. So when the users tries to deflect bullets, a Jedi instead has to deal with very hot goo coming at them at hypersonic speeds. This also doesn't cover that some energy weapons have large bore sizes. As attempting to block them would just cause an explosion that sets it's victim alight with plasma.

I can't believe it's not a Lightsaber
