All it takes is one seized deck plate, one stubborn gas cap, one snagged fishing line, one corroded canvas snap, one stuck drain plug, or one well-sealed wine cork, and the Boat Gadget more than proves its value.

Not to mention, its durable, rust-proof design means it will never corrode like your steel pliers, wrenches, and screwdrivers. Blue is avalable
