Inventor Ron Owen of Steven Plastics, Inc. developed and patented the original rotating tooth comb for the love of pets. Ron noticed that his dog Wilson would ‘flinch’ and pull away most every time he tried to untangle its matted hair. He noticed that pet hair was snagging and wrapping around the fixed pin and pulling on the hair follicle causing pain to Wilson and causing him to snarl and groan. An inventor by trade, he decided to build a new kind of comb spine that would allow the pins to move so that the pulling force on pet skin would be reduced. After many prototypes, he successfully designed a honeycomb spine which allowed each pin to independently rotate 360 degrees while moving up and down. As a result, he discovered that this constant pin movement and rotation significantly reduced the pulling force on hair and skin. The Untangler Rotating Tooth Pet comb was born. It has been manufactured and hand assembled at Steven Plastics Inc, Hoffman Estates, IL for 18 years+. Untangler manufactures a full line of Rotating Tooth Pet combs, Rakes and Brushes.
