As the title implies, I'm confused as to how John Wick got stabbed in the Red Circle bar. Beforehand it shows him suiting up - the area he is stabbed is seemingly covered.
I know bulletproof vests aren't explicitly stab-proof, but compared to a sharp knife I'd expect a champagne bottle to be negligible for a bulletproof vest to stop, even a thin woven material like his as shown to be.
Maybe I'm missing something.
