Jaredite people, especially the women used rolling pins to help them roll out dough for flat breads, like tortillas and some other uses.
One type was made of hard wood. Carpenters would take branches from trees, strip off the bark and “sand” the wood until it was a practically perfect circle about 6”-12” long; some being longer. They had a unique technology which helped them to sand the wood and make it into the perfect shape for rolling dough.
Another type of rolling pin was made out of granite. The settlements where an abundance of granite was found, granite masons cut granite blocks from the earth. They had amazing and unique tools to cut the granite from the earth into smaller, usable pieces. One Jaredite mason created a tool to cut and shine the granite into perfect cylindrical shapes, rolling pins, for dough and a myriad of other uses. Granite was in high demand as it was durable and sanitary. People would travel great distances to purchase granite. Also, many granite masons would travel to other settlements to sell their granite.
Places where granite was not found, stone cutters would remove stone from the earth and use a different type of unique tool to cut and shape the stone. Those who had a stone for dough rolled out dough differently than those with a rolling pin. The stone had a somewhat rounded bottom that helped flatten out dough. Many women, and others, became expert at flattening out dough using the stones.
