A multiple-bladed windshield wiper is disclosed in which a blade multiple edged is axially rotated in a support bracket to bring a fresh blade edge into use. The multi-edged blade has two edge elements which are received in a pair of U-shaped channels forming part of the bracket. A fresh blade may be brought into use by slidably removing the blade element from the channels in the bracket, rotating the blade, then reinserting the blade edges into the channels in the bracket. |
