Yes, and these sharp blades are made from steel. So it is the same.
except its not the same dude.
Daz Bones hasn't been shown to mould his body into any steel shapes other than slicing weapons.
If he can turn his body into a Shield Steel then sure its the Steel Fruit.
Until then, a Steel Steel Fruit doesn't exist in One Piece.
However there's no Paramecia fruit that would enthuse me. Seriously, it's either some material like fruit like Jozu had, allowing you to turn into it. I bet there could exist something like "Iron Iron no Mi" or "Copper Copper no Mi" - useless, as Haki users will easily penetrate through.
Not everybody is a Haki User so I don't think it would be useless.
You're only looking at this from a fighting perspective and One Piece has always been far more than that.
I'm not current with the story fully, but not far off.
So for logias I want to see, is the Sound Sound Fruit.
(Control over vibrations and the element sound being its standard power.)
I suppose an added bonus would be being naturally able to mimic anyobdy's voice you wanted to. Not so relevant since Mr.2 could do it but it would make sense to have it.
So you could vibrate your fist and hit someone at the same time doing extra damage or whenever your opponent tries to hit you physically, your body could vibrate violently so it hurt them.
As for a Zoan Fruit, Zoan Fruit: Cat Model: Panther. or Cat Model: Liger.
Ligers and Panthers are cool cats.
As for Paramecia? Not a clue.
Why I love this series so much. There isn't really a limit on possible DF's.
