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!** The Spork is 6.875" overall and has a blade length of 2.5".  It weighs 0.1 lb. Made in the USA.
