Dever Tom Thumb Bit.

The Sweet Iron Copper Tom Thumb is a popular bit amongst showjumpers and
eventers. It has a similar action to an American gag but without the
action of the mouthpiece being raised up in the horses mouth. The
mouthpiece of this bit is a combination of Sweet Iron & Copper. The
Copper players soften the joint & add tongue pressure. The Stainless
Steel cheeks give leverage, particularly if the reins are attached to
the lower ring. It encourages the horse to lower its head & also
provides brakes.

The combination of Sweet Iron and Copper makes this bit very palatable
and almost all horses will salivate and soften in response to the taste.
The loose ring Copper players in the centre of the mouthpiece are a
distraction & give the horse something to think about. This bit offers
a milder option when used with the smooth side of the mouthpiece facing
inwards; the stronger option is to use this bit with the Copper Ridges
facing inwards.
