Can you help me identify a German logo/symbol?

Here are some photos of an old German razor I got for $10 at a local antiques shop. Can anyone help me identify it? Is there a link or website with old logos for identification purposes? I thinks part of it says "assistance and education," but it's faint and faded.

The union of Metal Polishers and brass workers label was "Unity, Mutual Assistance, and Education"
Germany made razor for many different companies and stores and organization as well.

Thanks!! I thought that word might be mutual, but I could not make out the 1st word!
