The Kimblehook can be described as a fixed ring with the possibility to add leverage when you need it. The further down you place your rein; the more pressure will be added and divided between chin, poll, and mouth. The stable feeling Kimblehook creates can be good for fuzzy and worried horses that gets strong, unbalanced and hard to turn.
The Kimblehook puts the pressure further down in the mouth which can help a horse that gets too high in the neck.
Kimblehooks are always used together with a chain or strap behind the chin.
