Looks like it'd be easy to do on a small CNC, but probably not worth trying unless you can model it first and want a lot of them at once (or have a friend with access to a CNC).
. . and having clients with CNC I know what it takes to set up a job - multi-thousand dollar spoons are a bit rich for my taste. Of course quantity would bring that down but conventional machinery is far more practical for quantity production if you can afford the initial tooling.
Having been a machinist and having worked in both rework and tooling departments I'm convinced that a bench belt sander is one of the most powerful and versatile tools you can have. I've been planning to get one for some time. You can get small bandsaws and belt sanders for about $99 each these days and a bandsaw would also be useful for sawing up pig's feet and the like.
Precision surface grinders, centerless grinders, crush-form ginders, bench grinders, guinea grinders, etc. etc. - but they're hardly the right tools for making spoons. Some grinders are good for sharpening cutting tools though.
