I just found out that my food processor is one of the many that has the S-blade that's being recalled. My machine is around 10 years old, so it's not just newer models with the faulty blades.
To see if your Cuisinart food processor is on the recall list GO TO THIS PAGE and check.
The "form" they refer to later in the page is the box with the questionnaire near the top. If you click enough boxes the form will appear where you place your address so they can send the replacement blade.
