He uses his sword as a cane. So, yeah, like Phantom said, he carries it pretty much everywhere. It's not out of the ordinary for him to have brought it to that discussion.

I think he just wanted her to come clean so that he could actually discuss the White Fang with her and things like that, but he doesn't want her to know that he already knows what's going on with her and the rest of Team RWBY and the White Fang. If she knew, it'd bring up questions, and I don't think he wants them to know that he has been watching what has been going on. If they knew that, they'd become aware that he knows more than he's letting on, and he doesn't want to reveal everything he knows. He's pretty much in a position where everything is a game of chess, and if the other pieces on his side know what he knows, they may act in a way that messes up his plan and can land them in danger.
