About this puzzle
The most ordinary objects in a kitchen drawer have wildly different ages, and the ones that feel oldest often are not. Some of these solved problems that had existed for decades before anyone bothered - canned food, famously, arrived well before a decent way to open it. Patent years also reward the paperwork rather than the idea, which shuffles the order in ways intuition does not expect.
