how did Sima do this?


#1

I was just watching 3A Syndrome and it says that in his left hand he is using a Sigma Blade Zwie and it is starburst with a KK aluminum shim and responcive.
then in his right hand he is using a Sigma Blade Zwie also
and it is Dual O-Ring with a bind setting.
First how did Shima have a starburst responce in his left hand? and with a KK and aluminum shim how is it tug responcive?
then in his right hand there is a dual O-ring Sigma Blade Zwie so is there two types of zweis?
or is there another awnser?

What I am thinking is this - Special Edition, or perhaps he got it custom made. Anyway, the way it is responsive is probably thick lube.
