As the name suggests, it is mainly for hair that has been knotted by long-haired pets. The brush teeth have a metal blade that cuts the knotted hair.
How to use: Combine in the direction of pet hair growth. In order to avoid cutting too much hair, do not reverse the brush. It can be brushed once a week or every other week. Hold the knotted hair and gently comb it with the open brush on the remaining part. Do not use excessive force when encountering induration, so as not to pull off the fluff, but should hold the root of the hair and brush. When the fluff encounters the cutting edge, it is easy to break, and the force should be measured when brushing.
