Could also be that Klingon muscles are different from ours, they have a whole bunch of redundant organs after all, and the Batleth is designed to take advantage of their unique strengths
Physics does not work that way, you insolent fool!
Regardless of Klingon muscles, the fact that the blade sticks out sideways from the handle creates a lever arm that tends to make it droop due to gravity whenever it's held horizontally. Even if Klingon hands are different, they're not that different that it's somehow advantageous to keep torquing upwards so the blade points at the opponent instead of the floor.
Yeah it often is described by Klingons as a monastic weapon, meant to teach a lesson or discipline while training with it. I don't think the idea is for like a formation of Klingons to march into battle all wielding Bat'leths.
You train with a Bat'leth and then when a real battle comes you are more prepared to fight with other weapons, or even unarmed. It even makes sense in that the Bat'leth is a very complex object. I can totally see how simply trying to spar with it would force you to think more about all the different ways you can use the thing in your hands to your advantage.
I thought that was cannon? It's that not specifically mentioned somewhere? I can't remember when I heard it but I always thought that they were made to be hard to use, because winning a battle with a regular weapon is easy and therefore less honorable.
And if you watch the actors try to swing these things around they always look awkward.
Even worf seems to agree, by Picard s3 he has a sort of batleth / katana hybrid instead of a classic one. Though I think he already said in DS9 that he actually prefers the mekleth.
It’s a Mek’leth (modified in PIC S03), which he has stated before is his preferred weapon. He even uses it in The First Battle of Deep Space Nine to defend against the attempted Klingon invasion.
It's worth noting, too, that Worf is an in-universe badass even by Klingon standards. He easily takes out Duras. He won a major Bat'leth tournament in Parallels. He beats Gowron to the floor in Apocalypse Rising. Later in the Dominion War, he takes on every single Jem'hadar in a prison and beats them all, which Mar'tok can't help but be impressed by. Late in the war, he beats and kills Gowron easily.
If Worf says the Mek'leth is better, then we should take his word for it.
Also, Gowron is a chump ass bitch and I'm tired of pretending he's not.
