This $4.90 WiPal windshield wiper sharpener will have two types of fans. Of course there will be the folks who want to save a few bucks by making their windshield wipers last longer thus avoiding the purchase of overpriced wiper refills. The second market will be klutzs like me who can never get their old wipers out of the tracks. Simply slide the WiPal up and down your wiper blades to breath new life into the blade edge. Once sharpened, enjoy another few weeks of dry windshield. Only $4.90 – shipped from DealExtreme.
