Well, I read your site, and unlike Jilla, was able to grasp that these are discs of brushed aluminum that are in calibrated sizes and shapes common to gemstone cabs. You just wirewrap around the discs rather than "a slippery gemstone".
As an idea, I think it could have merit. As a person who loves tools, I like the idea. As a purchaser of tools, I think they are about $100 more than I would pay. I realize these are the collectible limited prototype sets, but unless they are gold, that price is way out of my range of consideration. (When I shop for tools, things fall into categories... some are priced such that I buy without hesitation, some are priced that I have to think about it some to be sure I will get return on my investment, some are priced such that I'd like to have it, but I'm going to have to save up for it, and some are priced such that I wouldn't buy it, no-way-no-how at that price. At $147, you fell into that last category.)
Website wise, I agree with some of the above posters. I would remove the 'Instructions for use" link, or make it work. The pictures enlarge when you click on them, but they still aren't very clear photos. Adding better pictures and some instructions would go a long way towards getting your concept across.
Good luck in your endevour.
