What is a significant feature of a mane pulling comb?

A mane pulling comb is specifically designed for the purpose of pulling, or thinning, a horse's mane. The significant feature of this tool is its thinner design compared to a regular comb. This thinner structure allows for a more precise grip on individual strands of hair, making it easier to remove excess hair without causing damage to the remaining mane or irritating the horse's skin. The pointed ends of the teeth can also aid in lifting and separating sections of mane hair for an effective pulling technique.

The other options describe characteristics that are not typically associated with a mane pulling comb. For instance, a wider-toothed comb would be more suitable for detangling rather than for the finer work of pulling a mane. Similarly, while robustness could be a feature of some tools, it’s not a key characteristic of a mane pulling comb which prioritizes finesse. Finally, although tail grooming is an important activity, a mane pulling comb is specifically built for grooming and thinning manes, not for applying to tail care.
