The Push Driver is designed to combine the different head sizes of screwdrivers into one convenient and intuitive tool.

There are various sizes and standards of screwdrivers that only experts or specialists can recognise, but does a regular household really need that many types of screwdrivers? The Push Driver is invented to combine multiple head sizes of screwdrivers into one convenient ‘push, and go!’ tool for the regular user.
To release and adjust the head sizes, unlock the pin and push downwards. Once the optimal head size is determined, lock the pin to secure the screwdriver. To make sure that the screws can be driven properly, two pipes are designed to cross each other — a structural mechanism that prevents the screws from mis-rotating.
