I have received this screw driver. But it doesn't have a 1/2" blade.
Seem like the description in the web doesn't quite match the
description on the box. I guess my search for a 1/2" blade screw
driver is not over.

1/2" is approximately 12 mm.

As long as you are close, it is more important that the thickness of
the blade match the slot, rather than the length.

The nice thing about the impact hammer is that it minimizes slipping
and will break corrosion to a certain extent.
