I think the greatest part about these products is the "viral" (for lack of a better word) ability. Someone with a new necklace will have all their friends asking about it... show their 10 BFFs. Same goes for cutbot and name tags. (See: http://blog.businessofsoftware.org/2009/07/seth-godins-talk-...) This is something that will be worth noting to people.
I noticed you were pretty specific with what you wanted in a co-founder on cutbots. Did you ever consider that you'd want someone with negotiation/supply chain management skills who has done deals [possibly in China] before? Or if you have before personally, even better. Just throwing that out there.
Lastly, a good way to get some attention and hype when your more finalized would be via http://www.kickstarter.com/. These seem like projects people would want to fund (in return for something... maybe first dibs?).
Good luck!
