Matt, Thanks! I made sure to try it on a practice piece to get a feel for it. Wasn't too bad. 
Lyle, Thank you! I'm going to try and make it this year. 
Chrishawk, I decided to go with hickory for the overlay so the stain would blend into them. It shoots great and is indeed smooth. I could actually get the tips slightly narrower but I don't want to scare my recipient.  

Chrisdrums, Theres always room to go a little more narrow.  

Thanks Sadiejane!
bushboy, Thank you! I think this profile has a lot of potential. I think I got away with a more circular tiller which really makes sure the tips are working even as narrow as they are.
