Which grooming tool is used primarily for detangling and smoothing the mane?

The grooming tool primarily used for detangling and smoothing the mane is the mane comb. This tool is specifically designed with teeth that can easily work through knots and tangles without pulling or damaging the hair. A mane comb allows for careful detangling, which is essential to maintaining healthy strands and a neat appearance.

In contrast, a dandy brush is typically used for removing dirt and debris from the coat, while a body brush is meant for grooming the horse's body and giving a shine to the coat. A hoof pick is specifically designed for cleaning out the hooves and would not be used on the mane at all. Each tool has a specific purpose, highlighting the unique function of the mane comb in mane care.
