Wincing at her reaction, Tim wished that it was easier to get people to trust him. He's been spoiled somewhat by Gotham, and he never thought that was possible. To the civilian there, there was only good and bad. Everyone had handy color coded gear. They were on the news. No one confused Robin with the Joker. If you're innocent, they're here to save you.

Not so, at present. Revealing you have a knife carries weight, because it means that you can kill them. Don't get weird about the knife, he wants to say, because I know exactly where to hit you with feet and hands to kill you, too. Because I've spent years learning how not to do crippling damage. I don't need the blade. You should be worried about me.

He doesn't voice it. He doesn't want to frighten her more. "I'm not going to use the knife if you don't want me too. I only thought that it'd be easier on you if it was more constrained. I thought we could bundle it up in strips of cloth."
