a way that I use to test harshness/feel of the bit that I make my students do is to lay the bit in the crook of your elbow then bend your elbow to see how it feels as someone "pulls back on the reins". Now imagine that was your mouth and not the inside of your arm....
This bit in particular when you do that wraps around the elbow joint and can be quite painful because there's no limit to the nutcracker feel - it's even stronger in that it will literally wrap around your arm
Exactly. That is how I was taught in Pony Club and have always carried that "teaching" with me. I remember at the Equine Affair that was held in Detroit Michigan a couple of years ago, I took a Bitting Clinic that was taught by the Myler Brothers - and the Waterford was one of the bits that we got to feel in effect first hand.
That bit hurts. It hurts more so than a slow twist single jointed snaffle.
it simply collapses where the horse tries to take advantage of the bit
Sorry, but it doesn't simply
do anything of the sort. This bit is designed to wrap around the horses lower jaw and it creates severe pain to the horse Just as CJ8sky explained. I don't want to sound like a broken record.
The exact way this bit was designed, is how it obtained it's well known name as the "Jawbreaker".
I dislike this bit, very much. Just as CJ8Sky said, this bit should only
be used when a horse has a specific, serious issue of rooting - only after the rider has done all they could to solve the issue firstly. I personally believe that majority of leaners can be solved by going back to the Training Scale, the rider using seat into legs into hands accordingly using a snaffle.
You give your horse something to lean into, they'll take it.
