In a large bowl, combine flour and salt. With pastry blender or 2 knives used scissors-fashion, cut in butter and shortening until mixture resembles coarse crumbs. Sprinkle in ice water, 1 tablespoon at a time, mixing lightly with fork after each addition, until dough is just moist enough to hold together. Shape dough into disk; wrap in plastic wrap and refrigerate 30 minutes or overnight. Preheat oven to 425 degrees F. On floured surface, with floured rolling pin, roll dough into 12-inch round. Ease dough into 9-inch glass pie plate; gently press against side of plate. Trim dough edge, leaving 1-inch overhang. Fold overhang under; pinch to form decorative edge. Line pie shell with foil and fill with pie weights or dried beans. Bake 10 to 12 minutes or until beginning to set. Remove foil with weights and bake 15 to 18 minutes longer or until golden. If shell puffs during baking, press it down with back of spoon. Cool on wire rack.
