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.
The swales have the effect of a weymouth and bradoon combination, but they are less complicated. You can ride with 2 reins, one rein on the normal ring for a soft support and the other rein on the bottom ring for the effect of the bar.
The Swales has loose rings for attaching the cheek pieces, so that the effect of the rein only affects the lower jaw. The swales are used (and supplied) in combination with a curb chain.
