The shank has an 8 1/4 overall length and a 5 3/4" active shank length. The #3 is a great mouth. This bit has a lot of lift without the bite of a sharp, narrow port. The port is completely "inactive" meaning that the port will never lock and come into contact with the horses palate. Skyline Bits are made from a focus on quality and comfort. The shanks are made from low carbon steel, and the mouth is sweet iron. When your horse is comfortable, they work well. All of Skyline's bits are made in Utah with the highest quality material available. This bit will be a long lasting, high performance piece!
