This is a comb to scrape through the wax on your board to rough it up for extra grip and/or clean and put on some more wax. My friends at Xpressiononthebeach gave me this. It acts as a a business card for a unique company in Muizenberg, South Africa called Wawawaves. They make old style traditional wooden surfboards, and some with a more modern flair. Very interesting site with some surfing history at www.wawawaves.com
