About the Forearm Bones design

Two bones stand shoulder to shoulder in heavy outline, the right one a near mirror of itself with flared knobs top and bottom and a pinched waist between them. The left one refuses that symmetry, its top shoulder cut square on one side and sloped on the other, its lower end drawn down to a blunt point. Where the two narrow waists pass, the gap between them closes to a slim pointed sliver, shaped like a leaf standing on end.
