These days, iPhones provide us with so many survival tools like a compass, a map and a flashlight but the iStab revamps the typical structure of iPhone cases by adding on a knife. Reminiscent of the Swiss Army Knife, this iPhone case was invented by Instructables member Mike Warren. His case has a built-in folding knife blade.
Warren used a standard design for folding knives and iPhone cases that he found on Thingiverse and mashed them up together in Meshmixer to create this glorious survival hybrid. He used Object500 Connex to print the new improved iPhone case.
This revolutionary iPhone case would come in handy for camping trips, hiking trips and for cutting packaging on the go. Forget having to rip things with your teeth as this new case will do it for you!
