The KA-BAR Spork, which is made from food and water approved Grilamid, is equipped with a fork/spoon combo and has a 2.5" plastic serrated knife in the handle. The knife is accessed by pulling the spork in opposite directions from each extreme end. Hint--avoid gripping the flat panel area in the middle of the Spork--this is actually part of its lock. The tighter you hold here, the more difficult it will be for you to pull out the knife!
