The Tacksmith Argentine Shank Curb Bit combines a classic western shank profile with a low port mouthpiece and solid copper inlaid roller. The Argentine shank allows both direct rein and leverage rein action depending on where you attach your reins, making it a versatile option for horses at different stages of training. The low port arch reduces tongue pressure, and the copper roller encourages consistent mouthing and saliva flow for better bit acceptance. Each bit is hand forged, assembled part by part, hand-welded, and polished to a mirror finish. The smooth, burr-free surface and precision forging mean no sharp edges that can irritate your horse's mouth. Available in 5.5-inch mouthpiece widths to fit a range of horses.
