I'm Sorry, But Lightsabers Are Useless Weapons
Trust me, I'm a Jedi
According to every census form I've filled out, my religion is listed as Jedi. So, according to the government of Canada, I am a Jedi, which gives me a little bit of street cred to weigh in on the ineffectual absurdity of the lightsaber.
Even those of you who have never seen Star Wars would be familiar with the ultra-rad plasma swords Jedi wield throughout the Star Wars universe. We have seen the raw power of these weapons as they slice droids and people in two like a hot knife through butter.
They even deflect blaster fire.
The question is, would I, as a Jedi, choose to fight with one?
Hell no!
Why Not?
Lightsabers have a massive flaw that every swordmaker throughout history has made sure to fix.
Swords have cross guards between the hilt and the blade to protect hands from injury. It took only a short time from the invention of swords to the realization that no cross guards equals missing hands.
