The Civvy, in plain edge, works well to impress waiters, as one very careless DC Knife Knut showed us at a luncheon a couple of years back. He closed it without paying attention and cut his finger badly, leading to an impressive amount of blood on paper napkins until we got the flow stopped. The poor waiter was staring at all of this with bugged eyes and his jaw down around his feet!
BTW, he then looked up "Knives For Sale" and found a plain edged Civvy for sale and bought it that same day! I think that it was "Love at First Bite".
