Unfortunately, we do not offer replacement blades. However, you can contact the official Philips spare parts warehouse directly. http://www.sertronics.ch/article/article.php3?art=31

I recently contacted Philips customer service for this very reason. I was told that the attachments were not for sale, but I was able to get one for free as a gesture of goodwill and replace my defective one. It's certainly worth a try, the customer service chat was friendly and pleasant.
