Are Saiyans Impervious to all weapons?

[Polyphase Avatron]

I doubt the swords used in DBZ are made out of the same material as those used to make swords in real life. There are probably vast numbers of different metals we aren't familiar with in the DBZ universe. Take Katchin for example.

My point is, even if someone 10x stronger than Trunks used a basic sword against Trunks, it would BREAK into pieces. There are metals in DBZ tougher than steel or Iron obviously. Not saying the weapon actually gives Trunks an advantage, NO, just saying that any knife you have in the kitchen right now, wouldn't be useful any battle even if you had super saiyan powers.

I'd be willing to test that out...

Depends on the metal to me...without ki amping I'd think any weaker metal would just break on them. A strong or enchanted thing could do the trick.

[Polyphase Avatron]

The winds from a tornado can drive a piece of straw through a telephone pole or a piece of wood through a steel beam. Even if the material is weaker, if the speed and force behind it is strong enough it can damage stronger stuff. Beerus was owning the Z-senshi with chopsticks even.

[Drayenko]

That's not about applying force, it's channeling ki through whatever you're using. Which is different.

[hleV]

Really any normal object could do a huge amount of damage if there was enough speed/force behind it.

Unless the person's body is taugher than the object, which is exactly the case here. A basic knife wouldn't pierce through a 1m³ of steel even if Goku tried that.

BOG is known for many stupid things.

It all depends on user, not the weapon...

I was thinking this as well. Maybe both Yajirobe and Trunks were channelling ki through thier swords which lets them cut through people/things they shouldn't be able to cut. I know in tenkaichi 3 that Yajirobe has a slash attack where it takes the form of a ki attack coming out his sword.

Also don't Trunks and Goten in dragonball online set up a sword training school. Maybe they teach how to channel Ki through swords.

The Same can be said for Goku when Trunks attacked him with his sword. He channeled his ki through his finger making it as hard as a rock

[Polyphase Avatron]

In an anime called Outlaw Star, one of the characters uses a wooden sword, but is capable of cutting strong metal and objects with it, due to being so fast, powerful, and skilled. I honestly wouldn't be surprised if Goku could cut a diamond in half with a blade of grass.

[Friezacooler]

Goku was hurt by Bulma's slap so i quess 10* Bulma's slap would have killed him or severely hurt him?.

Are you objecting my thought of a basic knife never being able to pierce through a 1m³ of steel or are you just being nit-picky about body vs object taughness?

[dbgtFO]

The sword isn't a part of the body, you can't channel your ki into it. Not until Goten and Trunks invent the swordsman school prior to the events of DBO, anyway.

Then why is there an aura around Trunks' sword?

Spoiler:

Did Trunks go to a tanning salon?

As for the topic:
A couple of days ago I saw a program on National Geographical Channel called "None of the above."
It's a program where the host tasks a group of people with predicting, what would happen in a given science experiment.
In one of the experiments there were four different vegetables(really fitting)*, that would be put into an air cannon and then fired off against a cutting board with speed of 800 km/h(or some other crazy speed like that).
Where normally a tomato thrown by a human would get smashed against the cutting board, on this occasion it burst through it, apparently its high water contents making this possible.

Like Rocketman's example this shows that 'weak' objects can be made vastly more destructible with greater force, which is what I always thought was the cause of Freeza's demise rather than Trunks' sword being some super sharp sword.

@OP
I think if a Super Saiyan was to wield a sword afainst another Super Saiyan of similar power, it would definitely cause damage.
In early DB that guy who along with the rest of his village were terrorized by Oolong, smashed his axe on Goku's head, but would it be the same result if Ox King had wielded it? I think Goku would have been cut in half!
Krillin also got cut by a rock or one of the namekian Dragon Balls, when Frieza blasted the Island, but would the same happen, if Dende had thrown the rock at him?
I really doubt that.
Also Goten throwing rocks at that big boulder behind Gohan had devastating effects. A normal person throwing a rock at a boulder would result in the rock being more likely to crack.

*Don't ruin it by saying tomatoes aren't vegetables
