SMA cable thumb screwdriver / key 8mm

Do you often work with HF cables with those SMA 8mm connectors? Especially when many of those are tightly packed, it can be tedious to work with them.

Here comes in my idea for a screwdriver. A wide slit on the side allows you to easily slide it on the cable and rigged surface ensures good grip. The entrance is slightly widened for easier use and less need for tight tolerances. If you're using rubber-covered connectors, you might need to scale the model up a bit; it is designed for 8mm size.
