All you'll need is a clean cutting board, a sharp knife, and a kitchen towel (or paper towel). First, pat it dry and lay it on the board skin side up. Grab a bit of the skin on one end of the filet and use your knife to gently slice the skin away from the flesh. Use a towel to grip the skin if you need it. As you continue to evenly and gently slice under the skin down the filet, pull away the skin as you go. Discard it or keep it and fry it with a bit of oil and salt for crispy salmon skin!
