You missed the whole argument, Mr. ZKK
King uses his sword to make fire dragons, it's not a CUTTING TECHNIQUE
Fujitora uses his sword to send meteors and gravity pressure, it's not a CUTTING TECHNIQUE
WB uses his sword to send meteors, it's not a CUTTING TECHNIQUE
Big Mom uses her sword to cast Misery, it's not a CUTTING TECHNIQUE
Whether or not Shanks uses his fiery sword is a bullshit argument because his main attacks come from his CoC, and he uses his sword to send blasts of CoC, which doesn't fit the criteria for swordsmanship skills, BECAUSE IT'S NOT ONE CUTTING TECHNIQUE
I know your brain is limited to the point of believing the ZKK bullshit theory, but this is going overboard, I'm practically typing 2+2=4, even primate brains like you can reason this out.
