Kimblewick bit

First invented by show jumper, horse man and family farmer, Felix Oliver (Aka Phil) Mr Oliver & his family lived at Meadacre Farm, Kimblewick, and started a partnership with Harry Payne, from Bushey, that was to make his reputation with such great horses as Red Admiral, Red Star, Sheila, Galway Bay and Planet.

After his retirement from the farm in 1974 he lived in Longwick where he took immense pleasure in schooling and advising young riders.

[2] The "D" ring is offset, so the bit mouthpiece is on the upper part of the flat side of the D, creating a small amount of leverage, supported by a curb chain.

Depending on the position of the rider's hands, the standard Kimblewick has different effects when the rein is allowed to slide freely along the curved portion of the D-ring.

[2] However, one popular design, the Uxeter Kimblewick, has slots in the curved portion of the ring, so that the rein may be fixed into one position.

Kimblewicks are regarded by some people as unconventional or non-"classic", and the compromise design that combines snaffle and curb features may lead some horses to either overflex in the bit or learn to lean on it.
