This pendant consists of a trio of items, with the main one being a pineapple grenade, also known as an MK 2 grenade. The cap above the pin can be pulled to release a small stainless steel blade which could be used for all sorts of handy situations. This necklace comes on a simple, break-away ball lanyard that allows for the wearer to easily tug the necklace free, if need-be. The neck knife measures approximately 3 inches long. Each piece is created from cast metal and fits perfectly around any size neck.
