Remove *Show Top Sites* icon from bookmarks bar

Has anyone figured out a little hack to remove the "Show Top Site" icon that sits on the far left of Safari's bookmarks bar (I'm using v 7.0.3 (9537.75.14) running Mavericks). I presume I'd need to change some deep file, but I'm willing to break stuff to get rid of it.

(again, I'm referring to that actual 12-dot icon, just to the right of the "Show sidebar" icon. I want it gone)
