Begging your pardon, but is it appropriate to call the handle of the trident a tine? If not, then your example is flawed, having the form of 

      |      |
      |      |
      |      |
      |      |
       \    /
          |
          |

Oughtn't it be more like

     |   |   |
     |   |   |
     |   |   |
     |   |   |         ?
      \  |  /
         |
         |

(Not that I could ever dream of composing either, mind you)

P.S. If it helps anybody's presentation - the commands [ pre ] and [ /pre ] but omit the spaces will permit spaces in text to be preserved in posts.
