fake dhs w968 w997 theory

one theory says that the only real w968 and w997 blades are the ones with computer printings.
the pics of ma long's blade have this computer letters so this is their main backup for their theory.

the other ones it's not known where they come from or if they even are national blades.

this one below would be real national blade too

this is ma long's blade

again ma long's blade, you can see it has the computer letters.
