Titanium for the handle- so, I guess it's a framelock... See, a piece of info you didn't want to divulge might have been 'leaked'. ;-) But it is something a prospective maker of the prototype should be aware of. When you ask something like that, it would be a good idea to lay out general info that might be relevant for the one who makes it (say, pivot bearings which adds difficulty to prototyping, or recurve which might be difficult in terms of sharpening, compound bevels, &c)- what Frank asked was AFAIK entirely for the benefit of your getting the answer you're looking for... Except, you might have gotten a few advice from experienced knife-makers on your design*, which IMHO is not a bad thing.
I think you worry too much about that- I don't think there is much in knife world that hasn't been done or cannot be said to have been in a way done before.
P.S. I'm currently designing few locking mechanism 'improvements' I'm considering to offering to a major knife company- and it's not the prospect of the ideas being 'stolen' that terrifies me... it's the prospect of them laughing their head off when they see them... :-D
* except for the ideas and the knife design I'm proposing- it's my first knife, and if they don't realise it's the bestest knife in the world, and the bestest construction there ever was... it's their fault

(all kidding aside, I did post some ideas of mine and all I got in return were helpful responses and considerations... not anyone bothered to steal my design :-( ).
