• Use a Tail Guard. One of the best ways to stop razor tail is to install a tail guard at the end of a deck. They add a buffer between the tail of your deck and the ground, hence prolonging the deck's life.
• Sand Your Deck heavily against the edge to flatten the edge. As you sand down, you will remove the thin pieces of wood, which are called veneers. You'll see the board beginning to get its shape back as you continue to sand. It is the easiest and fastest way to repair a razor tail and will only remove about 1/8-inch of your tail.
• Avoid dragging your tail for stoping or nose slides and manuals.
• Apply Carbon Fiber thin layer at the bottom of the deck for added strength.
