Razorwhips are Sharp Class dragons that have the ability to slice through rocks and trees with their wings. They have metallic silver scales and a large horn on their heads, and appear to have a serious underbite. Heather has one in Race to the Edge named Windshear. According to Heather, their fire can melt a human's flesh from one hundred feet away, and they can also shoot razor-sharp spines. Windshear proved that these can tear large holes in ships.
