These are the current stage of design. The shape of Lake Superior already works. So does Washington. Go Seahawks. Michigan works but is too big and needs some work.
I'm asking you because I'd like to know what other geographical regions or other shapes you'd like to see for sale. South Africa is on the way, for example. All of Africa could work. Australia. Mexico. It takes some finagling, but if it looks like it might conceivably work, we can probably turn your favorite thing into a bottle opener that you can eventually bequeath.
The other question is on the key attachment. The stainless steel cable eliminates the need for a key ring and is tough as hell, but requires a larger hole and costs slightly more. The wire triangle is tougher than it looks, but wouldn't hold you up if you were to use your bottle opener as a wedge for trad climbing gear. Which would you prefer?
If you've got ideas or requests of shapes you'd like to see, post them here or email me at email@example.com.
These are not free to make. So, if you're willing to pitch in toward development costs, you'll be the first to get one, probably made out of delightfully haggard 1/8" stainless steel or 1/4" mild steel (like the ones in this photo).
