What finish for teaspoons?

[Primvs Aebvtivs]

Hi folks, may be a crazy question, but I've been asked if I can turn teaspoons... Now, that answer is a "give it a go", but my problem is, with hardwood handles / metal bowls, not much of a problem geting the handles wet. BUT if it's a one piece spoon, how do I go about treating / coating the wood so the bowl isn't going to swell up everytime the drink is stirred?

Wood available will be :- Silver Birch, Beech, Apple, Walnut, Pine, Buddleia (sp?). Any suggestion on best type to make spoons out of?
I have Boiled Linseed oil, and Tung oil to hand, but don't think an oil based finish is suitable...

Any help will be gratefully received!

Not much is going to work.. silverplate might. If you insist on wood use maple or cherry. the others will take on too much water.
