Carbonator Cap Wrench

This Thing provides a comfy grip and more leverage for installing and removing the Liquid Bread Carbonator Cap. Ref: http://www.liquidbread.com/retailservices.html
If you use one of these caps as much as I do, your hand bones get tired of twisting the hex shape directly. Carbonator Cap Wrench to the rescue!
Also in the picture is rev 1 which was kind of sharp, so it's not included.
