Hand operated kitchen appliances are made for today with yesterday's design.
In the 1700's, all household chores were done without electric appliances or tools. As a homesteader, it's not that you don't use electricity it's that you don't have to.
Our non electric appliances make food preparation for cooking or canning quick and efficient with minimal clean-up. If you have a generator as a backup for the grid, a fireplace as backup heat, a shovel as a backup for the snowblower, you need to give serious consideration to "backups" for the kitchen. These household items, including the laundry helpers, are perfect for emergency situations where the electricity is down for a period of time.
