I don't see a knife
Is that an idiom ? ("Put the knife down homey")
The body language he has is common for knife display, at least here in America. They palm the knife or box cutter, present it furtively, low and tight so there isn't a scene, and then both guys decide what will happen. Kali figured he could punk this guy, and the guy probably wouldn't make a fuss like calling the cops. It didn't work out that way I guess.
He pulled out a knife talking about Jason Blaha back in the day too. Back when Blaha was living his commando fantasy.
