I near fainted when I saw this, I thought surely this is NOT for real, people actually use this on a horse? Here I was thinking we where past thinking up new ways to torture horses. Bloody hell, how bad does your horses mouth have to be to make you think using one of these is a good idea? Or worse, how bad are your hands and riding? I pity any horse that has this put on them. FARRRRKKK MEEEEE...............BIKE CHAIN>>>>#( I am not going to post the link to where I found these, just in case some stupid person thinks their a good idea. If you look at these and think for even 1 second that you horse needs this bit then stop right there. Send your horse to a professional trainer for re-mouthing and you right along with the horse for re-educating.
