Does anyone know of the Z tool used to be able to buy from AAA of Iowa. is the tool still around? any can tell me a part number with a company name I can buy this from? 
different manufactures have different names for the tool you're talking about. the toll that i call a "Z" tool has a 3 inch end on 1 side and a 2 inch on the other and a little hook on each side. i'm assuming this is the one you're speaking of, great little tool by the way.
you can order it from a million different people, here's a couple.
the baprod link is for BA Products. i've dealt with their tools before and they are pretty decent. i've never dealt with the other one.

i think the one you're talking about is the "zinger" with this manufacturer. BA calls it the "over/under" or "double grabber".
