Honestly I’m a bit a loss to explain this gadget. It’s a screwdriver housed inside a plastic grenade. It has six different bits you can switch out. I can’t even imagine any possible scenario where you’d need to stash a screwdriver inside a fake grenade. Maybe it’s meant to be ironic because grenades blow things up and screwdrivers put things together (except when they’re unscrewing things in which case the whole joke falls apart)? Call in the Mystery Machine because we’ve got a live one here.
