  This seems a tad elaborate when simply prying the shell open will suffice.
And one can always use the jaw or an available crevice as a "third" hand. Or

  Little steps are often the hardest to take.  We are too used to making leaps 
in the face of adversity, that a simple skip is so hard to do.  We should all 
learn to walk soft, walk small, see the world around us rather than zoom by it.
