26. Screwdriver's hand use
It's difficult to work if your vision is blocked or you're in a dark room. Moreover, it's inconvenient when you have to hold the flashlight in one hand while keeping the device with another. Instead, you can now use rubber bands or stick a keychain flashlight into the screwdriver's hand. It will provide the light you need. You can now use both your hands during work and avoid dropping the screw all the time.
