My Doc Martens. The design of a shoe is pretty well worked out, but the devil is in the details, and my Docs have been carrying my fat ass through deserts and snow and jungles and cobblestones and pavement for twenty years, and I got em used. That's not just down to materials, it's down to design.
The Gerber Chameleon (and its Remix followup) pocket knife design. (https://www.gerber-tools.com/Gerber-Remix-22-01969.php) Absolutely brilliant - the pivot itself is a ring, so when you use the knife you have zero chance of slipping and cutting yourself, and instead of a side to side motion for cutting, you just use your hand naturally, the way you would a handsaw.
And the iPad stand and mount I use, whose brand escapes me. It folds compact to fit in a bag and the legs and main clamp separate for easy carrying, but the feet pivot outward or can be used, when pivoted inward together, as a base that can be slid into a holder (that came with it) or anything that can hold it up. I often slip the feet behind the vertical pipes in our kitchen to watch videos while I'm doing dishes, and I've built a lap desk that uses pipe strapping to allow me to slide the stand feet underneath the desktop, so the iPad itself doesn't take up any space at all on the desktop - it's just hovering over it like an IKEA worklight. Fantastically simple and useful design.
