US Patent 9807978 Grooming apparatus and knot remover

A pet or human battery operated grooming apparatus having a housing, a number of tines formed in the housing, each tine having a slot, and a number of disk shaped blades mounted to a shaft, the shaft mounted in the housing and the blades disposed in the tine slots. A protective cover encloses most of each blade leaving only a slit open to the blade. The tines direct knots or tangles in the hair or fur of the pet, or hair of a human, to the slits and the blades. The user may then rotate the blades to cut the knots. This process occurs without any undue pulling of the associated skin of the animal or human.
