Shaun,
I think you have a good idea and I wish you all the best. When so many tool manufacturers are disappearing or being bought out it's essential that some 'new blood' comes along to redress the situation!
I will, however, without in any way wishing to 'piss on your strawberries' offer some advice:-
Almost the first question you were asked concerned the country of origin! Your answer was perfectly valid, but I think you somewhat missed the point. While I have no doubt that some folks want to buy American made tools (and drive American muscle) simply because they are American, the majority know that the issue is far more important than that, namely that making a tool in the U.S. is the best way to obtain a high quality item!
Tools, especially relatively specialist items such as this, generally fall into two groups. The first are made by small specialist firms to a high standard, and sold in small numbers over a long period of time, generally to professionals at whatever price it costs!
The second group tend to get "outsourced" at the earliest opportunity, generally to the cheapest place in the universe. They end up being sold as little more than 'novelties' and usually leave in their wake a lot of DIY'ers who chuck it in the trash, and a few pro's who feel frustrated they can't get a decent one! I think your idea deserves better than to wind up in the second group!
You may feel, as many others have before, that by manufactuing in China or wherever, you can control the quality and get what your customers want! Believe me, you'll struggle! I have seen products, especially tools, being outsourced for over 30 years and not one of them, NOT ONE, was ever to the same standard as before, and many will not even perform the function they are supposed to.
For that reason alone, I no longer buy tools made in China, and I regret that will include yours! If you are able to get them made 'somewhere sensible' (U.S, U.K, Germany - it actually doesn't matter so long as it's somewhere that can turn out decent tools) you can put me down for a set!
Good luck!
