Loose Ring Sweet Iron Jointed Snaffle is a dark color metal and is designed to rust. As it rusts, it produces a sweet taste that horses like. The single joint puts pressure on the sides of the tongue, on the lips and on the bars due to the nutcracker action. The loose ring makes a more mobile bit than an eggbutt or fixed cheek bit, which should encourage your horse to keep a relaxed jaw and mouth the bit. The loose ring may be useful if your horse leans on the bit, or takes hold, as the bit is always movable so the horse cannot take hold as easily.
