Unscrew

This revolutionary invention extends the concept of screw to new horizons.

Ordinary screws are designed for both screwing and unscrewing, and have to make compromises to provide good performance for both purposes.

By focusing only on unscrewing, a specifically optimized head shape can be designed, which maximises the torque that can be applied to the head without excessive stress,using the provided unscrewdriver.

Although the unscrew is primarily intended for use cases where screwing is not required, it may still be possible to screw it if you really want to (with a hammer).
