Waveblade works by a patented oscillating action that cleans with agitation rather than friction. Unlike putty knives, pressure washers or scrubbers Waveblade's vibration is safe for any surface and will not wear away protective paint. Barnacles, calcification rings, tube worms, mussels, oysters, rust and slime are all removed easily. The tool is equipped with a 45 foot cord and works up to 15 feet underwater or on dry land.
