Arras Theme – Removing the post header

Hi guys, i’m new to wordpress, please to meet you all. So my problem is regarding this Arras theme, it’s really nice. But i have one problem though.. When I insert a new post, I want to remove that “header” (sorry, I don’t know exactly what it is called) which gives options to post on Facebook, Digg It! etc…

I searched through all the theme’s php code, but couldn’t find a decent way to remove it.

Thanks for any help

Good day
