Ok I stand corrected these are NOT tetrapods. Sorry for the confusion

  Well, confusingly, the last picture on the blogpost look (to my untrained eye) to be tetrapods. Those are 'tetrahedral' (ish) shapes. In contrast, the https://en.wikipedia.org/wiki/Dolos https://en.wikipedia.org/wiki/Dolos (plural 'Dolosse') are two tapering cylinders at right angles to each other. They have the same symmetry, but a different structure. Does that make any difference to how effective they are? No idea! edit: When I said the "same symmetry" of course I should have said the dolos has some of the symmetries of the tetrapod (subgroup?).

    Maybe the form variations were just for patent circumvention.
