The Henderson Equine Castrating Instrument by Stone is a patented equine veterinary instrument developed from the original Henderson cattle tool and refined for horses. Its new jaw design is specifically engineered for equine use, with a reverse tapered shank that aids retention in keyless type chucks. Built from stainless steel with a Teflon coating, it resists rust, is easily sterilized, and is fully autoclavable; a removable pivot bolt enhances cleaning and sterilization. Used on tens of thousands of horses with excellent results, this horse equipment is a reliable choice for equine castration procedures.
