is a 3D printed iPhone cover which has a folding knife along one edge, producing a blade whenever you might need one. This phone case is "cutting edge", and is designed as an exploration in conceptual 3D printed weapons.
I based this idea from are free, and the programs needed edit the 3D files are also free: Netfabb
is a great way to keep a cutting implement on hand at all times. This can be used as a weapon for self-defense for the next time you're in a knife-fight like Michael Jackson in Beat It
, or harmlessly used for everyday actions like opening packaging or cutting items to size. Forget highly-contentious 3D printed firearms and flimsy iPhone knuckle dusters
, the iStab
has you covered for all your cutting needs.
Here's what I used to make my iStab
3/16" (5mm) rivets
scrap of felt
Dollar Store paring knife
3D models: folding knife + iPhone case (both free)
access to 3D printer
