Introduced in 1856, the Turtleback was a significant milestone for Singer as it marked their first sewing machine specifically designed for domestic use.
It held the distinction of being the first reliable lockstitch sewing machine available on the market, capable of effortlessly stitching through multiple layers of fabric.
This model broke away from the traditional heavy cast steel construction by utilizing lightweight cast aluminum, resulting in a machine that weighed a mere eleven pounds.
These machines are highly regarded for their robust steel construction and their ability to perform zigzag stitches, which adds versatility to their capabilities.
