The spade bit is a historic vaquero design for a type of curb bit with straight, highly decorated shanks and a mouthpiece that includes a straight bar, a narrow port with a cricket, and a "spoon," a flat, partly rounded plate affixed above the port, supported by braces on either side.
Considered a highly technical piece of equipment to be used only on a finished horse, the spade bit is a refined tool that experts compare to driving a sports car in its ability to convey precise commands to the horse.
In the vaquero tradition, its use represents the highest level of trust and communication between horse and rider.
[3] Its emphasis has always been on producing a finely tuned working horse and partner, emphasizing quality rather than on how quickly the goal is reached.
[1] A light bosal called a bosalito remains on the horse by tradition, usually without reins attached.
