The twisted wire bit is a bit made to be abrasive and painful. No matter how light you think your hands are, how much you love your horse or how tough your horse is this will and does hurt. The only people who use these bits are brainless hillbillys, animal abusers and people who don't know any better. You are selling a torture device. Why? I don't know. But I suggest you stop because you're letting animals get hurt.
