[TheForge] Forging blackberries?

[Shannell Sugrue]

A customer want some blackberries like these

in a railing, the picture is taken from page 88 of the  book "the
contemorary blacksmith" by Dona Meilach, Im sure many of you will know it, i
the nota says it was made with a clam shell die. Im looking for tips on
making these, I can do balls with a clapper die but I can only think of how
to make these blackcurrents in 2 halves and mabey join them together ie: by
sinking a half blackcurrent depression into a block of steel and then
hitting a hot blank into that with a flat top die on the P.hammer. even then
I think the part of the berry closest to the top of the depression would
have little detail because it isnt being hit into the die, more being
squeezed sideways into it, and thats only if the blank is the right size. I
cant see any way you could rotate a ball in a "clamshell" die to get an even
effect. Anyone done these before???
