Thought about something interesting lately, so decided to share it here. It's about the process of forging a black blade.
> We first heard of
forging a black blade when Zoro was fighting the fox, with the keyword
"forged" picking Zoro's interest
> Later on though, during Zoro's training, Tenguyama once again referred to the keyword
"forged into" a black blade
And
forging literally means to
make, create or build into something with Ryuma doing through his history of battles
But what is particularily interesting about knowing this is while trying to compare it to the levels of hardening Oda introduced in his manga
> Level 2 hardening allows to create an invisible armor for defense or offense purposes
> With Level 3 hardening allowing to penetrate interiors and thus with the potential of changing their shape
Reminds you of something? Yes, the process of
forging a sword into a black blade. I think then that this process is related to level3 hardening, except that it requires continuous usage to eventually permanently turn the blade into a black one
