The Keyzmo is just slightly larger and thicker than your typical key—for good reason. It’s purposely thick enough to not bend, crack, or break when tightening and loosening even the most stubborn screws, bolts, or nuts. It’s also large enough to give you enough torque to properly secure or loosen those screws, bolts, or nuts, yet small enough to easily fit on your keychain and put in your pocket.
