I made one years ago, bowl was made from redheart, stem from ebony. It smokes very well, although a standard vulcanized stem might have been
a better option as the texture of the ebony feels slightly strange.
My Dad has it now, will try to get a pic if I can remember.
BTW I 'carved' the bowl out with a forstner bit, and mostly shaped it with a sander, so not a lot of knife work went into it.
