Try to use a Robertson and you will absolutely destroy the screw. That shot of the screwdriver tip fitting the screw precisely is what is important.
The screws are TERRIBLE quality. The WiHa screwdrivers in the link utilize every last load bearing surface of the screw head. Trouble arrives when screws arrive so tight loosening them is next to impossible.
I have a full set of WiHa Robertson screwdrivers and I would love to read where someone thinks they do not work in these morphidite screws because they (the tools) are inferior.
