We have a limited quantity of the agitator blade.  It fits Hamilton Beach models 30, 33, 40DM, 930, 933, 940.  This is a used, reconditioned item.  The agitator is easy to replace.  Simply unscrew the broken blade by gripping the shaft (which has some protectivea cloth around it) with pliers.  Fold up the blades, grasp the closed blades with channel lock pliers and unscrew.
