100 °crevice screwdriver / crevice screwdriver

100 °crevice screwdriver
100 °crevice screwdriver

The newtype crevice screwdriver is a combined with 100* and an ordinary screwdriver.When equipments I operated damaged, and common screwdriver can't repair them, this time can only use screwdriver with angle to repair the equipment.

How do I think of this? When I mainten and repair a suitcase, I found equipment can't be repaired by a
common screwdriver , a screwdriver with angle. But why 100 °? Because we think screwdriver and screw need a suitable rotation and radial force .So that the user can acquire the most convenience and comfort.
