This Weaver Leather Stierwalt Calf Breaking Halter features figure-8 nickel-plated hardware designed by Kirk Stierwalt that allows for quicker pull-and-release action to help prevent swollen jaws often caused by the slower release of a conventional breaking halter. Unique hardware also helps prevent the poly rope from rubbing together for easy sliding action while still preventing the halter from slipping off. Satisfaction guaranteed.
