Bright red with seed-like cutouts and a green handle, this knife looks the part to slice watermelon easily and efficiently. Extra long in length to tackle even the largest melons, the knife has an extra-sharp serrated blade to cut through tough rinds and a nonstick coating to make neat slices that release from the blade. The matching sheath lets the knife travel safely for slicing up melons at picnics or for camping trip snacks.
