An elegant, slimmer-than-usual version of the classic pocketknife housed in anodized aluminum with a blade, a nail file, a screwdriver and scissors. It even has a key ring for easy access. The color is the limited-edition part — a shade of red “inspired by the strength and resilience of weathered stone” — with the year 2025 printed on the back, so consider it a tiny collector’s item to keep in your car or throw in the back pocket of your jeans. (But not to take through airport security.)
