How do I prevent catching edges on rails with my park board?

Three steps: First, detune (dull) the edges between your bindings using a gummy stone or file—sharp edges in this zone are the primary cause of rail catches. Many park boards come pre-detuned from the factory. Second, choose a rocker or flat profile board, which naturally lifts the contact points off the snow and reduces edge engagement on features. Third, focus on proper technique—keep your base flat on rails and avoid leaning onto your edge. With a detuned, rockered park board and proper technique, edge catches become rare.
