A gadget is a small mechanical device or tool, especially an ingenious one. That is the dictionary definition and it undersells the category completely. The objects that belong here are not gadgets in the cheap sense — the impulse-buy trinkets that end up in a drawer. They are the objects that have earned a permanent place in pockets and bags because they are simply better than anything else at what they do. A Zippo lighter. A Victorinox knife. A shoe that fits like it was made for the street you're walking on. Gear that goes everywhere and comes back ready for more.
The H7E Lab gadgets network covers the objects that matter. Not every object. The ones with history, with craft, with a reason to exist beyond filling shelf space.
