To address your points: I'm not sure where to find someone with this expensive machine. I know where to find Shapeways.com pretty easily. And as I wrote above regarding your second paragraph, a precisely-printed key surely is more reliable (and easier to make) than the bent sheet metal and grocery loyalty cards.

I agree this argument is silly. Whether an Ikon SK6 lock is considered "umbumpable" and by who is pretty subjective. But this thread began with a commenter saying that none of this is news, and that it's all 50 years old. Hyperbole is indeed pretty annoying.
