This is from their website:
"SK Tools USA, LLC is now a sister company of Shop-Vac USA, LLC in Williamsport, PA USA. We have relocated our manufacturing and distribution from Sycamore, IL to Williamsport, PA USA in November 2021. This move allows us to leverage the facilities and technical capabilities of Shop-Vac who also shares our pride of quality, precision, innovation, service, and country.
Under the ownership of GreatStar Industrial USA and its portfolio of brands including Arrow Fastener, Pony Jorgensen, Goldblatt we now have far greater resources and global scale to improve our service and innovate while building on our 100-year reputation. We will continue to manufacture many products in our new Williamsport facility while leveraging the experience and resources of Shop-Vac and our parent company, GreatStar Industrial. This blended approach will allow us to focus our manufacturing, procurement and innovation while improving our service and maintaining our reputation as the premium tools for American professionals."
So it sounds like they make a few things in their USA facility but they don't say what exactly. But yeah, they most likely moved hand tool production to Asia.
