@goldensky - Lucky you! I love California naval oranges. The gadget you received is called a citrus peeler, not a julienne peeler. It's used to peel a variety of citrus fruits.
The pointed tip is used to slice the peel and the other end is used to get under the peel and pull it away from the fruit with greater ease.
I only paid one dollar for mine and I use it everyday for peeling oranges and grapefruits. You're going to love using it once you get the hang of it.
