The wiper blade is the entire assembly attached to the wiper arm (#30, #31 in the illustration). Though many feel you should just replace this, the OEM Acura ICON-style blades have replaceable inserts ("Blade, Rubber" according to the parts guide) that are easily and economically replaced. Anyone can do it, no special skills or tools are required.

The parts "Blade, rubber" are identified as #21 and #23 in the parts illustration.
