Our Kenwood triblade hand blender chopping blade addon, started to show first signs of wear (after ten years!). The triblade propeller shaft was not running freely there was some sort of gunk in it.
So I wanted to disassembly the thing but for the prop/ triblade part that wasen't so easy. There are six notches on the inner plastic casing/ bearing to turn it, but for that you need a tool in order to have enough force to turn and push it out.
This tool helped me to do that (in the pictures shown is a version of the tool that has a incorrect prop/ blade cutout I corrected that in the uploaded version).
