Sweet iron will rust when it comes into contact with (air) humidity; the surface rust tastes sweet and naturally stimulates the saliva production. This will cause the horse to salivate more which in turn encourages better acceptance of the bit. The rusting process (oxidation) changes the blue colour of the TRUST-bit to a brownish-grey.
If a sweet iron bit is not used for a while, an orange-brown rust layer may develop on the mouthpiece. Simply remove this by wiping the bit with a damp cloth.
About Baby Pelham :
The pelham is delivered with short and long shanks. A bit with short shanks is called a baby pelham in Dutch. A pelham with long shanks is a normal pelham. This bit can be used with one or two reins.
You can also use a pelham strap, this connects the bit ring with the ring a the bottom of the sides. A pelham strap connects the two reins, so just one rein is needed. The effect is a bit softer than riding with two reins. The pelham is used in combination with a curb chain.
The pelham is often used with strong horses. Because of the leverage effect created by the sides, the bit is pretty sharp. By using this bit it’s easier to ride a horse rounder in the neck. The longer the sides, the sharper it is.
The pelham is not suitable for inexperienced riders or horses.
The mouthpiece thickness is 16 mm, some are also availbale in 12 mm.
