As far as bank accounts go, the wife and I have a "his", "hers" and "ours" thing going on. As long as all the bills are paid thats all that matters. However, right now we are in saving mode so the money I spend on knives or anything that isn't normal like a hair cut and oil changes, etc. gets a little more scrutiny. I just got a package from Amazon yesterday and my wife said, is that another knife? It was a tube of nano lube. His, hers and ours works well for me and my wife. Mainly because the "ours" account doesn't get touched without both of us agreeing on it.
