The tom thumb bit offers more precision and control due to the lifting effect in front which can assist the rider in helping to sit the horse back on its hocks, combined with poll pressure from the leverage action. Can be used with one rein on either the snaffle ring or the lower ring or with two reins.
The brass alloy roller link in the centre of this bit can help to calm and focus horses as well as aid salivation.
In good used condition. The sweet iron has oxidised but this is completely normal after use,
