The bit is the traditional Icelandic 2-part bit with D-ring also called muffebit, with the lock-up system.
In the middle of the bite there is a unique lock that prevents damage to the palate as the bite cannot break.
The bite is made of blue Sweet iron, which oxidizes easily (rusts) and thereby promotes acceptance of the bite.
Available in sizes 10.5 cm and 11.5 cm
