        Great curb for horses that don't need much leverage. Perfect fit for a small Morgan or Arab.

        What bits are made of...

        If you have any questions about this product or a type of bit, please contact us at 1-800-365-1311 or service@sstack.com
        Stainless Steel

        Bits are most commonly made of stainless steel. Stainless steel can be cleaned and polished repeatedly without damaging the finish. It is strong, durable, and flavorless and does not impact salivation. Some stainless steel mouths are inlaid with copper.


        Copper encourages salivation to increase the sensitivity of the horse’s mouth. It warms up quicker than stainless steel in cold weather.

        Sweet Iron

        Sweet iron is cold-rolled steel. The material appears rusty after repeated use. This oxidation tastes sweet to the horse and increases salivation.  


        Rubber softens the action of the bit as it is softer than traditional metals. Rubber-covered bits are generally thicker than metal.   


        Aluminum is lightweight and easy to maintain.


        Plastic bits are softer than traditional metal bits and they are durable. Many plastic bits are scented or flavored.

        Nickel Silver

        Nickel silver is a nickel alloy, also known as German silver. It encourages salivation for a more sensitive and supple mouth.
