To fillet the carvings, you need a variable radius fillet. I've just filleted your model in Rhino and it works OK. I thing Michael is thinking of adding variable radius fillets to MoI.

Thanks for interesting Steve:i imagined a variable fillet..
at the end of my post i told to use Mike's technique,and he aswered to you in the same way
you can post the filleted carved base in Rhino,to see results,if you want
about Michael i say:let him in peace enjoy Christmas holidays..it's a-one man band- (best wishes Michael !! )
i'm 49 years old and i still believe in Santa Claus,last four years i wrote my letter to him asking everytime the same thing:t-splines in Moi
Someone say that Santa Claus don't exist but i want to believe...maybe soon or later...dreams come true...

Mike here is your stuff





left part looks like a "snake cobra-neck"
it needs to put the right hand thumb when hold the handle
i say to model just half handle:the left bulged part,trunkated in the middle like i did,not like photo
i also attach rails and sections to sweep the handle i used, we can mantain proportions,so you can start
make it magic...Mike !!!
