Neevil's Amazing Multi-Use Grenade

This small, hand-held bomb is made of a number interlocking pieces, like a three-dimensional jigsaw puzzle. When assembled completely, the specially treated surface makes for a perfact grip. This item was purpotedly first created by the legendary goblin inventor Neevil, although he denies any interest in techno-magical combinations. This item is one of several new technological devices that have cropped up in recent years, melding goblin mechanical know-how with gnomish magical enhancements. After the grenade explodes, its pieces pull themselves out of whatever they're embedded in, crawl across the floor, and reassemble into the original grenade. If any of its parts cannot reach the main body in time (say, they flew off the side of a cliff during the explosion or sank into a lake), the grenade's magic is lost.
