Double Jointed Bits
Double-jointed bits reduce the nutcracker effect because they conform better to the horse's "U" shaped mouth, instead of the "V" created by a single joint. In this respect they are milder, and many horses prefer a double-joint over a single joint.
Many of the double-jointed bits (especially the French link and Dr. Bristol) are occasionally "added to" by twisting the cannons of the mouthpiece. This greatly increases the severity of the bit, as these cannons act directly on the tongue and bars in addition to the regular action of the bit. A relatively "kind" French mouth can therefore be turned into a severe bit when the cannons are twisted or if the mouthpiece is put onto a gag bit. All references below are based on the cannons being smooth, not twisted.

Famous quotes containing the words double, jointed and/or bits:
“Because I have work to care about, it is possible that I may be less difficult to get along with than other women when the double chins start to form.”
—Gloria Steinem (b. 1934)
“Entrance and exit wounds are silvered clean,
The track aches only when the rain reminds.
The one-legged man forgets his leg of wood.
The one-armed man his jointed wooden arm.
The blinded man sees with his ears and hands
As much or more than once with both his eyes.”
—Robert Graves (1895–1985)
“They’re semiotic phantoms, bits of deep cultural imagery that have split off and taken on a life of their own, like those Jules Verne airships that those old Kansas farmers were always seeing.... Semiotic ghosts. Fragments of the Mass Dream, whirling past in the wind of my passage.”
—William Gibson (b. 1948)
