Bottle Grenade is basically a bottle opener. Apart from the basic function, this grenade shaped Bottle opener can function as a screw-driver and wrench. Instead of trashing the cool looking bottle caps, now with Bottle Grenade, you can wear them. Currently the designer is intended to make only aluminum based grenades but after the successful project at kickstarter, he’s planning to produce it with Stainless Steel, Titanium, and other tough metals.
