The KA-BAR Tactical Spork-Knife
This great little tool from KA-BAR separates into two very helpful eating utensils. Made from a food-safe material called Grilamid. The plastic serrated blade is 2.5" long and is rigid enough for an overcooked steak, and sharp enough to get through a raw tomato. Classic KA-BAR grip style.
Weighs in at one tenth of a pound, so you don't have to worry about adding precious ounces to your rucksack.
