EDC Utility Knife – Swappable Shells

OverviewI wanted to make a printable utility knife… but also give it some personality.The core design is simple, clean, and functional — it fits a standard utility blade, feels good in the hand, and goes together with just one M3 bolt and nut. But the themed liners really bring it together. I’ve made four inspired by versions: a Rebel pilot, an Imperial agent, a classic pink doughnut, and a NASA engineer. It’s a practical tool with a bit of character — and way more fun to keep around on the bench or in your pocket.
