My eyes must bug out a little when I read through some of our catalogues at work (I work at a tack shop). Both english and western, some of the things they come up with is insane.
Try an offset double twised copper wire (why the copper I don't know) short shank gag.
What about a chain mouth long shanked gag with chain curb action and rawhide nosepiece?
You thought I was kidding?
Bike chain gag, anyone? And yes ma'am you can slide that sucker almost to the horse's ears if you wanted to.
...makes me feel almost silly for cringing at the single twisted wire we do bring in and hide at the back of all the bits (sometimes we get an irate cowboy demanding such a thing)
