I think the most common misconception in scuba is that a knife is a tool... WRONG!!! Knives are weapons and shall be yielded as such! Every diver that thinks of themselves as macho should have at least 1 knife larger that 8" (serrated edges optional). I myself carry 2 Seahawks (13" of testosterone) "wild west" fashion with a USD Vulcan tucked away "just in case".
Of course anyone who says otherwise should have 1 hose promptly sliced (sorry, another downfall of a single hose regulator). And if that metro-sexual loser also states that you are trying to compensate (ladies included... but somehow I don't think any are reading this thread) for a "shortfall" ... shall immediately receive a Mike Nelson karate chop to the neck.
