It works if a horse has his nose stuck out, but if he is inclined to curl under it will make him worse. It works on the nose, and also by squeezing the lips against the teeth while still having the effect of the bit. I used it on a strong little mare out hunting, but would think that in a schooling situation as Risky Business said, it would make a good temporary assist.
yes, our trainer had my spouse use one on her jumper. An OTTB that is a perfect gentleman at home but gets jacked the first time in a new show ring (or take your pick of 100 other "reasons"). worked really well.
There was a horse at my barn that showed in one because he tended to get really strong and pull the girl around. It worked really well at first, because she only used it at shows, and would use a regular noseband at home. When the girl started to use the kineton at home as well, the horse got used to it and therefore did not respond as well to it.
It can be a helpful tool in the right hands, but only as a temporary fix.
I used one (well, my daughter did ) on a hot little TB jumper mare who would invert and run to the jumps if given half a chance. She would duck behind a stronger bit, but the kineton worked well - to a point. A little beetle hackamore with sheepskin over the nose turned out to really do the trick for her though.
They work really well on horses that get above your hands or ones that stretch out in front of your hands, if they tend to curl under not so good. I've used them on hunters, just schooling, who have soft mouths but want to get heavy. I use a kineton as one of those "surprise! you're not hanging on me today!" pieces of equipment.
I tried one many years ago an a very strong jumper. Useless. Put it in a box. Tried it again on a racehorse in training. Useless. Put it back in the box. Then had a client dump a bunch of tack at my barn, stuff that she could not be bothered to pick up and take home. Guess what was included? Now I have two of the dam things, equally useless.
I hate to be one of THOSE people who swears by Micklems, but seriously, have you tried one? If you use the bit clips, the action would be pretty similar to the noseband Burgie posted. Might be worth a try. If it doesn't work, you can normally sell them pretty easily.
Trying a life outside of FEI tents and hotel rooms.
LOFF my kineton. Nancy, I'd be happy to buy one (or both) of yours, lol!
Used it on my hot chestnut TB mare who hates being told what to do and hates anything harsh. Worked like a charm to rate her. It was easy as pie to go from a hand gallop to a nice bouncy little canter. Most important, it didn't make her mad!
I also use it as an "emergency brake" on the older gelding I lease if I haven't ridden in a while. It offers a little extra to keep him from getting nutty.
Like all break-assist gizmos - treat it with respect. If the horse does not get any relief when he responds, he will learn to run through that, too, just like he runs through his normal bit. Also, just thinking, there should not be any sharp edges on the teeth, since the kineton has a pinching effect...I can visualise mashed cheeks.
