Gasp!!!!
Tim!!! I gotta say my heart stopped in reading this way unusual title!
OK, we'll leave it 'anatomical'
in analogy. I always think of the poor Victorians with the 'ballock' daggers, and thier desperate attempt to liken them to a more prudently acceptable anatomical part, the kidney.
I will say incredibly 'interesting' items, and good note on the motif linked to centipede tracks. I always appreciate that kind of insight on the symbolism found on weaponry.
All the best,
Jim
