Was in a meeting where we needed to hook the laptop up to the projector only the data cable was coiled up near the wall and zip tied. Guy asks me if I have a knife and I pull out my ZT0777 that I was carrying that day (I don't usually cut zip ties with a knife, but we didn't have anything else).
One guy looks at me and says, "How did you get that through the gate? YOUR THE GUY THEY'RE LOOKING FOR!"
I laughed and explained that when I went through the gate, the guard usually asks me about the dead bodies in the back. We laughed.
Still, non-knife people are a little unsettled when they see a sharp mid-sized knife. I mean, I don't consider the 0777 to be a big knife by any means. Not like the 0600, which I wasn't carrying that day (rarely carry it since it feels too big for me).
