KitchenAid Blender Cutter Blade Assembly

I just replaced my old Cutter Blade Assembly with this and it works perfectly. I do see a trace of grease on the underside after use, as I did on the original, but no leak of the contents. After seeing the grease on the new one, I'm not sure that I even needed to replace the old one, as it is on the outside and did not cause a leak or contaminate the contents. At any rate, I now have two Cutter Blade Assemblys and both work fine.

After searching for the above piece, finally I found it here in Amazon. Thank you for your service and promptness.
