The ADI profuct line is made in China. Sometime around 2018, the ADI line replaced the FSV (forged steel vise) line. The FSV line was made in Taiwan. Although the ADI and FSV share the same general form factor and red color, they are not the same. According to my inquiry with Yost and published specs, the ADI vises are stronger than the FSV. That said, the ADI is made in China according to Yost.
