Wera 05003433001 T x 20 x 154 mm "Kraftform Kompakt VDE 67i" Inter-Changeable Blade - Silver

All good

A1

It's not cheap but its excellent quality and worth it.

This is a real Robertson screwdriver blade - not a cheap "square head" knockoff. Robertson heads have a slight taper that holds the screw properly.#1 is also known as a "green" Robertson.#2 is also known as a "red" Robertson.

Wanted to fill the gap in my set as this was one size missing from my kit. Great quality as are all Wera screwdrivers from this range.
