For cutting in the same direction of the "flutes" (those little lines running down the surface), we use a coroplast cutter, but you can get the same results with a metal straight edges and utility knife.

For cutting "across the flutes" cuts, you use a straight edge or metal ruler and a utility knife - nice steady hand. To score it, press down with the knife only part way through the coroplast. Be sure the knife is straight up and down. Press down harder to cut all the way through, keeping pressure on the straight edge. Good luck!
