Instead of exploding things, this grenade is used to put them back together. When you pull the pin on this plastic bomb, you will reveal six different stainless steel screwdriver heads - three Phillips and three flat. Choose the head you need for your project, insert it in the socket, and close the grenade for a helpful tool. The grenade comes on a key ring, so you can carry it with you and be prepared to save the day for any mechanical emergencies.
