Folowing Ironraven's astute advice, I've added Silcock keys to my home and auto BOB's. Problem is they're so darn heavy for a single purpose item. Too heavy in my opinion for an EDC bag. So my question is, does anyone have a source for a lightweight alloy Silcock key? Failing that, do you think a Wave Tool is an adequate substitute for EDC carry? Ironraven, are you out there?
