Looks to be severe, but when ridden with a medium to tight curb the mouthpiece lays flat on the bars, over a wide area, touching more and many new nerves. Used successfully on horses with damaged tongue or bars. Unique floating shank allows curb to be drawn from side to side for another totally new feel. Many who have tried it say it works OK the first day, better the next and by the end of a week cannot believe the control they have regained. "Lifetime Guarantee"
