In Extremadura - Spain - the word "CABRESTO" is leather, rope, rope Ribbon. . . that unites the e browband headstall that uses the animal in the head, with the hand of the person who runs it, so if it is mounted on it, as if you move it from "cabresto" directing it where it has to go. Tends to be sufficiently long for which also you used as "whip" to herd it. I hope that explanation has clarified them the meaning of this word so of daily use at other times. Best regards.
