This Pirate Necklace Dagger Knife has a 3 1/4 inch blade. The blade is exposed by pulling the top of the Pirate Weapon and is replaced using the metal strip attached to the top. Simply line up the metal strip and place the raised button into the slot at the bottom of the blade, push, and it goes back into the bottom part of the necklace. The pirate knife necklace is just over 5 inches long, and has a chain that is about 13 inches long when attached to the necklace. Beautiful detail on both sides with a pewter type finish and is of excellent quality. It is a unique piece to add to your pirate collectibles.
