For training and behavior modification, whips can be a useful tool for a horse handler.
Things to Consider:
Good grip -- Select a whip that is easy to handle. Some have wrist loops, which help secure it when riding.
Training -- Most horses will learn to respond quickly with whips. Trust is the key to a horse submitting and obeying their owner.
Cleaning -- Leather whips can be preserved for a long time by applying a good leather cleaner and conditioner.
