Ancol Ergo Maxi Knot Buster dog groomer. These products are excellent devices for getting rid of small areas of entanglement in pets fur. Use carefully as the blades are sharp.
To use the Knot Buster, identify a knot or mat. The Knot Buster should be pulled slowly upwards through the coat and moved back and forth to gently detangle stubborn knots. The blades will have a cutting action on knotted hair. 
The Knot Buster is cleverly rounded, ensuring your dog stays comfortable while being groomed. The Ergo Knot Buster is particularly useful on long-haired dogs that are likely to get tangles and matted fur. 
Ensure the blades do not go near your dog's skin by keeping the rounded side against the dog's body. 
To ensure your dog has an enjoyable grooming session, start slowly and gently. Pause or end the grooming session if your dog becomes agitated.

-Perfect for removing knots from long, silky, and curly coats
