The all-new Zen from Ant Design aims to be the “ultimate” in customizable modular multitools. It takes on a simpler Swiss-Army-knife-inspired folder form than modular multi-folders like the Roxon or Goat, ensuring fast, simple tool swapping and deployment. Optimize your own singular ultimate everyday multitool or swap implements in and out depending on what your calendar has in store.
I like the idea, and others have tried it, but no one has quite nailed the execution yet.
