SharePoint 2013: Hiding the Blog Tools Web Part

Problem
You want users to have contribute rights to your blog site but do not wish to show the Blog Tools on the post pages. If you remove the web part, other blog web parts (e.g. Categories) do not work. If you modify the Blog Tools web part properties and select the Hidden property, the web part still renders.

Viewing the web part properties in the page (via SharePoint Designer) shows that the web part should not be visible and should be hidden:

BUT IT STILL DISPLAYS ON THE PAGE!

Solution
Modify the Blog Tools web part properties as follows:

1. Change the Height to a fixed height of 0 pixels
2. Change the Chrome State to Minimized
3. Change the Chrome Type to None

Click OK and Save (or Stop Editing) the page.

Refresh and the Blog Tools web part is still on the page but does not show!
