Tool box opener thingy

I don't know exactly what to call it, but it's what you twist / pull / use a key on to open it.
I know that Xiaowu said that he wanted a simple toolbox, but I was working on the opener and got this far, and thought this looked cool.  You'd twist to open (although I don't think there would be any reason to).
Do you want to keep this, or continue with the old lock?
