Engraved German Silver 7-1/2 inch Flat Shank 5" Medium Port Sweet Iron Curb Bit Description This is an engraved German Silver flat shanked bit with a medium port 5 inch wide x 3/8 diameter sweet iron mouthpiece. The wide medium port curb is considered to be a mild level 3 type bit. The shanks measure 7-1/2 inches in length and the purchase measures 3 inches for a 2.5 to 1 leverage ratio. The bit weighs a nice lightweight 13 ounces. With a medium degree of leverage, this shank bit provides an indirect curb rein action designed to be used with a curb strap attached to the purchase. The Independent Swivel Cheek purchase is a feature that allows the purchase of the bit to be independently attached to the mouthpiece and the shank; when the rider engages one rein, the shank moves but the purchase has a slight swivel in order to prevent pressing directly into the horse's face as the bit moves below it. The medium port featured on this mouthpiece allows the horse to swallow when he is moving forward and relaxed. I will leave feedback after receiving feedback as confirmation that item has been received.
