A blade tool that is useful for removing and installing blades into and out of a cutter head which is rotatably mounted in a thickness planer. The blade tool consists of a handle and a hook portion. This hook portion is designed to pull or pry blades away from the cutter head when removing the blades from the cutter head. The handle of the blade tool defines a curved portion that is designed to press against the edge of the blade when installing the blade into the cutter head. The blade tool may further comprise a magnet coupled inside a cavity at the end of the handle. The magnet is designed to extract the blade away from the cutter head once it has been loosened by the hook portion. In one embodiment, the magnet is a rare earth magnet.
