The shank has an 8 1/4 overall length and a 5 3/4" active shank length. The flat port #1 mouth is a great advance in chain,ported bits. It is a great bit with a lot of feel. Works well in most horses mouths. We have used it on rope, barrel, sorting, and ranch horses with great results! 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!
